Ligand-dependent activation of transcription in vitro by retinoic acid receptor alpha/retinoid X receptor alpha heterodimers that mimics transactivation by retinoids in vivo. (1/6391)

All-trans and 9-cis retinoic acids (RA) signals are transduced by retinoic acid receptor/retinoid X receptor (RAR/RXR) heterodimers that act as functional units controlling the transcription of RA-responsive genes. With the aim of elucidating the underlying molecular mechanisms, we have developed an in vitro transcription system using a chromatin template made up of a minimal promoter and a direct repeat with 5-spacing-based RA response element. RARalpha and RXRalpha were expressed in and purified from baculovirus-infected Sf9 cells, and transcription was carried out by using naked DNA or chromatin templates. Transcription from naked templates was not affected by the presence of RA and/or RAR/RXR heterodimers. In contrast, very little transcription occurred from chromatin templates in the absence of RA or RAR/RXR heterodimers whereas their addition resulted in a dosage-dependent stimulation of transcription that never exceeded that occurring on naked DNA templates. Most importantly, the addition of synthetic agonistic or antagonistic retinoids to the chromatin transcription system mimicked their stimulatory or inhibitory action in vivo, and activation by a RXR-specific retinoid was subordinated to the binding of an agonist ligand to the RAR partner. Moreover, the addition of the p300 coactivator generated a synergistic enhancement of transcription. Thus, the dissection of this transcription system ultimately should lead to the elucidation of the molecular mechanisms by which RAR/RXR heterodimers control transcription in a ligand-dependent manner.  (+info)

Differential plasma membrane targeting of voltage-dependent calcium channel subunits expressed in a polarized epithelial cell line. (2/6391)

1. Voltage-dependent calcium channels (VDCCs) show a highly non-uniform distribution in many cell types, including neurons and other polarized secretory cells. We have examined whether this can be mimicked in a polarized epithelial cell line (Madin-Darby canine kidney), which has been used extensively to study the targeting of proteins. 2. We expressed the VDCC alpha1A, alpha1B or alpha1C subunits either alone or in combination with accessory subunits alpha2-delta and the different beta subunits, and examined their localization immunocytochemically. An alpha1 subunit was only targeted to the plasma membrane if co-expressed with the accessory subunits. 3. The combination alpha1C/alpha2-delta and all beta subunits was always localized predominantly to the basolateral membrane. It has been suggested that this is equivalent to somatodendritic targeting in neurons. 4. In contrast, the alpha1B subunit was expressed at the apical membrane with all the accessory subunit combinations, by 24 h after microinjection. This membrane destination shows some parallels with axonal targeting in neurons. 5. The alpha1A subunit was consistently observed at the apical membrane in the combinations alpha1A/alpha2-delta/beta1b or beta4. In contrast, when co-expressed with alpha2-delta/beta2a, alpha1A was clearly targeted to the basolateral membrane. 6. In conclusion, the VDCC alpha1 subunit appears to be the primary determinant for targeting the VDCC complex, but the beta subunit can modify this destination, particularly for alpha1A.  (+info)

Solution structure of BID, an intracellular amplifier of apoptotic signaling. (3/6391)

We report the solution structure of BID, an intracellular cross-talk agent that can amplify FAS/TNF apoptotic signal through the mitochondria death pathway after Caspase 8 cleavage. BID contains eight alpha helices where two central hydrophobic helices are surrounded by six amphipathic ones. The fold resembles poreforming bacterial toxins and shows similarity to BCL-XL although sequence homology to BCL-XL is limited to the 16-residue BH3 domain. Furthermore, we modeled a complex of BCL-XL and BID by aligning the BID and BAK BH3 motifs in the known BCL-XL-BAK BH3 complex. Additionally, we show that the overall structure of BID is preserved after cleavage by Caspase 8. We propose that BID has both BH3 domain-dependent and -independent modes of action in inducing mitochondrial damage.  (+info)

1,25-Dihydroxyvitamin D3 induces differentiation of a retinoic acid-resistant acute promyelocytic leukemia cell line (UF-1) associated with expression of p21(WAF1/CIP1) and p27(KIP1). (4/6391)

Retinoic acid (RA) resistance is a serious problem for patients with acute promyelocytic leukemia (APL) who are receiving all-trans RA. However, the mechanisms and strategies to overcome RA resistance by APL cells are still unclear. The biologic effects of RA are mediated by two distinct families of transcriptional factors: RA receptors (RARs) and retinoid X receptors (RXRs). RXRs heterodimerize with 1, 25-dihydroxyvitamin D3 [1,25(OH)2D3] receptor (VDR), enabling their efficient transcriptional activation. The cyclin-dependent kinase (cdk) inhibitor p21(WAF1/CIP1) has a vitamin D3-responsive element (VDRE) in its promoter, and 1,25(OH)2D3 enhances the expression of p21(WAF1/CIP1) and induces differentiation of selected myeloid leukemic cell lines. We have recently established a novel APL cell line (UF-1) with features of RA resistance. 1,25(OH)2D3 can induce growth inhibition and G1 arrest of UF-1 cells, resulting in differentiation of these cells toward granulocytes. This 1, 25(OH)2D3-induced G1 arrest is enhanced by all-trans RA. Also, 1, 25(OH)2D3 (10(-10) to 10(-7) mol/L) in combination with RA markedly inhibits cellular proliferation in a dose- and time-dependent manner. Associated with these findings, the levels of p21(WAF1/CIP1) and p27(KIP1) mRNA and protein increased in these cells. Northern blot analysis showed that p21(WAF1/CIP1) and p27(KIP1) mRNA and protein increased in these cells. Northern blot analysis showed that p21(WAF1/CIP1) and p27(KIP1) transcripts were induced after 6 hours' exposure to 1,25(OH)2D3 and then decreased to basal levels over 48 hours. Western blot experiments showed that p21(WAF1/CIP1) protein levels increased and became detectable after 12 hours of 1,25(OH)2D3 treatment and induction of p27(KIP1) protein was much more gradual and sustained in UF-1 cells. Interestingly, the combination of 1, 25(OH)2D3 and RA markedly enhanced the levels of p27(KIP1) transcript and protein as compared with levels induced by 1, 25(OH)2D3 alone. In addition, exogenous p27(KIP1) expression can enhance the level of CD11b antigen in myeloid leukemic cells. In contrast, RA alone can induce G1 arrest of UF-1 cells; however, it did not result in an increase of p21(WAF1/CIP1) and p27(KIP1) transcript and protein expression in RA-resistant cells. Taken together, we conclude that 1,25(OH)2D3 induces increased expression of cdk inhibitors, which mediates a G1 arrest, and this may be associated with differentiation of RA-resistant UF-1 cells toward mature granulocytes.  (+info)

CRE DNA binding proteins bind to the AP-1 target sequence and suppress AP-1 transcriptional activity in mouse keratinocytes. (5/6391)

Previously, we have shown that nuclear extracts from cultured mouse keratinocytes induced to differentiate by increasing the levels of extra-cellular calcium contain Fra-1, Fra-2, Jun B, Jun D and c-Jun proteins that bind to the AP-1 DNA binding sequence. Despite this DNA binding activity, AP-1 reporter activity was suppressed in these cells. Here, we have detected the CREB family proteins CREB and CREMalpha as additional participants in the AP-1 DNA binding complex in differentiating keratinocytes. AP-1 and CRE DNA binding activity correlated with the induction of CREB, CREMalpha and ATF-1 and CREB phosphorylation at ser133 (ser133 phospho-CREB) in the transition from basal to differentiating keratinocytes, but the activity of a CRE reporter remained unchanged. In contrast, the CRE reporter was activated in the presence of the dominant-negative (DN) CREB mutants, KCREB and A-CREB, proteins that dimerize with CREB family members and block their ability to bind to DNA. The increase in CRE reporter activity in the presence of these mutants suggests that CRE-mediated transcriptional activity is suppressed in keratinocytes through protein-protein interactions involving a factor that dimerizes with the CREB leucine zipper. In experiments where the A-CREB mutant was co-transfected with an AP-1 reporter construct, transcriptional activity was also increased indicating that a CREB family member binds AP-1 sites and represses AP-1 transcriptional activity as well. Exogenous expression of the transcriptional repressor CREMalpha down-regulated both CRE and AP-1 reporters in keratinocytes suggesting that this factor may contribute to the suppression of AP-1 transcriptional activity observed in differentiating keratinocytes.  (+info)

Impairment of the proapoptotic activity of Bax by missense mutations found in gastrointestinal cancers. (6/6391)

We have reported previously that codon 169 of the proapoptotic gene BAX is a mutational hot spot in gastrointestinal cancer. Two different mutations were found in this codon, replacing the wild-type threonine by alanine or methionine. To compare the proapoptotic activity of these Bax mutants with wild-type Bax, we established an ecdysone (muristerone A)-inducible system in cultured human embryonal kidney 293 cells. Addition of muristerone A induced a dose-dependent decrease in the viability of cells transfected with wild-type BAX, but this loss of viability was inhibited in cells transfected with BAX mutants. Furthermore, muristerone A induced morphological changes characteristic of apoptosis, including cell shrinkage, rounding, formation of apoptotic bodies, detachment and nuclear condensation and fragmentation, in cells transfected with wild-type BAX. These hallmarks of apoptosis were clearly diminished in cells transfected with BAX mutants. Mutation of threonine 169 did not affect the binding of Bax to Bax, Bcl-2, or Bcl-X(L). These results demonstrate that missense mutations at codon 169 of BAX are functional because they inhibit its apoptotic activity. This is the first report of the functional significance of missense mutations in BAX, or any other proapoptotic member of the Bcl-2 family, in primary human tumors.  (+info)

Auxiliary subunits operate as a molecular switch in determining gating behaviour of the unitary N-type Ca2+ channel current in Xenopus oocytes. (7/6391)

1. We systematically examined the biophysical properties of omega-conotoxin GVIA-sensitive neuronal N-type channels composed of various combinations of the alpha1B, alpha2/delta and beta1b subunits in Xenopus oocytes. 2. Whole-cell recordings demonstrated that coexpression of the beta1b subunit decelerated inactivation, whereas the alpha2/delta accelerated both activation and inactivation, and cancelled the kinetic effects of the beta1b. The alpha2/delta and the beta1b controlled voltage dependence of activation differently: the beta1b significantly shifted the current-voltage relationship towards the hyperpolarizing direction; however, the alpha2/delta shifted the relationship only slightly in the depolarizing direction. The extent of voltage-dependent inactivation was modified solely by the beta1b. 3. Unitary currents measured using a cell-attached patch showed stable patterns of opening that were markedly different among subunit combinations in their kinetic parameters. The alpha2/delta and the beta1b subunits also acted antagonistically in regulating gating patterns of unitary N-type channels. Open time was shortened by the alpha2/delta, while the fraction of long opening was enhanced by the beta1b. The alpha2/delta decreased opening probability (Po), while the beta1b increased Po. alpha1Balpha2/deltabeta1b produced unitary activity with an open time distribution value in between those of alpha1Balpha2/delta and alpha1Bbeta1b. However, both the alpha2/delta and the beta1b subunits reduced the number of null traces. 4. These results suggest that the auxiliary subunits alone and in combination contribute differently in forming gating apparatuses in the N-type channel, raising the possibility that subunit interaction contributes to the generation of functional diversity of N-type channels in native neuronal preparations also.  (+info)

PER and TIM inhibit the DNA binding activity of a Drosophila CLOCK-CYC/dBMAL1 heterodimer without disrupting formation of the heterodimer: a basis for circadian transcription. (8/6391)

The Drosophila CLOCK (dCLOCK) and CYCLE (CYC) (also referred to as dBMAL1) proteins are members of the basic helix-loop-helix PAS (PER-ARNT-SIM) superfamily of transcription factors and are required for high-level expression of the circadian clock genes period (per) and timeless (tim). Several lines of evidence indicate that PER, TIM, or a PER-TIM heterodimer somehow inhibit the transcriptional activity of a putative dCLOCK-CYC complex, generating a negative-feedback loop that is a core element of the Drosophila circadian oscillator. In this report we show that PER and/or TIM inhibits the binding of a dCLOCK-CYC heterodimer to an E-box-containing DNA fragment that is present in the 5' nontranscribed region of per and acts as a circadian enhancer element. Surprisingly, inhibition of this DNA binding activity by PER, TIM, or both is not accompanied by disruption of the association between dCLOCK and CYC. The results suggest that the interaction of PER, TIM, or both with the dCLOCK-CYC heterodimer induces a conformational change or masks protein regions in the heterodimer, leading to a reduction in DNA binding activity. Together with other findings, our results strongly suggest that daily cycles in the association of PER and TIM with the dCLOCK-CYC complex probably contribute to rhythmic expression of per and tim.  (+info)

KCTD21 (potassium channel tetramerization domain containing 21), Authors: Dessen P. Published in: Atlas Genet Cytogenet Oncol Haematol.
The existence of functional GPCR heteromers represents both a major challenge and an opportunity for neuroscience and drug discovery. The number of GPCRs for which evidence suggests a functional role of heteromerization is rapidly increasing. Given the large number of GPCR genes, their ability to form combinations raises the daunting possibility that there are tens or even hundreds of thousands of unique receptor heteromers in the brain and nervous system. Elucidating the function of each of these potential distinct receptor complexes represents a considerable challenge.. ...

N1 - Open Archive. PY - 2009/1/30. Y1 - 2009/1/30. N2 - Oligomeric assembly of Brca1 C-terminal (BRCT) domain-containing mediator proteins occurs at sites of DNA damage. However, the functional significance and regulation of such assemblies are not well understood. In this study, we defined the molecular mechanism of DNA-damage-induced oligomerization of the S. cerevisiae BRCT protein Rad9. Our data suggest that Rad9s tandem BRCT domain mediates Rad9 oligomerization via its interaction with its own Mec1/Tel1-phosphorylated SQ/TQ cluster domain (SCD). Rad53 activation is unaffected by mutations that impair Rad9 oligomerization, but checkpoint maintenance is lost, indicating that oligomerization is required to sustain checkpoint signaling. Once activated, Rad53 phosphorylates the Rad9 BRCT domain, which attenuates ...

Together, the results from this study provide evidence for B1 receptor homo-oligomerization and the importance of this mechanism in the expression of the receptor on the cell surface of HEK293 cells. This mechanism directly translates into the presentation of a constitutive mechanism for cellular signaling through Gq/11-mediated phospholipase Cβ activity. Such homo-oligomers may be a regulatory point in B1 receptor maturation, and their disruption could provide a unique way for silencing signaling through this and other B1 receptor-stimulated pathways during inflammation.. Multiple methods were used to investigate whether B1 receptors form homo-oligomers in HEK293 cells. Although neither of these methods alone is sufficient to prove oligomerization, together they are consistent with such a mechanism. Higher order oligomeric receptor forms were readily apparent on immunoblots of SDS-PAGE gels. Such complexes were also indicated by coimmunoprecipitation of differentially tagged receptors. ...
Thermochemistry of HO2 + HO2 → H2O4: Does HO2 Dimerization Affect Laboratory Studies?: Self-reaction is an important sink for the hydroperoxy radical (HO2) in t
In the field of neurobiology, there is great discussion about which particular species of amyloid-beta oligomers (AβOs) contributes to the pathogenesis of Alzheimers disease (AD), a progressive neurodegenerative disease. Previously, our group has found, using molecular weight cutoff filters (MWCO), that AβOs are primarily 100-300 kilodaltons (kDa). The goal of this project is to verify this finding using size exclusion chromatography (SEC). SEC can be used to determine AβO molecular weight according to the amount of time it takes the AβOs to pass through the SEC column. Overall, the project yielded results showing significant portion of AβOs are either |1300 kDa or around 13 kDa. We are currently investigating further reasons why the MWCO and SEC data yield very different results.
The present work is one of the first characterizations of multimeric intermediates in protein aggregation, and offers direct information about the assembly process. The results of the Ellman assay confirm that the dimer is linked by a disulfide bond, as previously proposed (Manderson et al. 1998; Bauer et al. 2000). Formation of the dimer therefore requires at least unfolding of the proteins main helix (Qi et al. 1997), which protects the free cysteine from the solvent in the native structure. We have previously shown that the Blg oligomers are productive intermediates in aggregation: assembly of aggregates coincides with consumption of oligomers, and purified oligomers at high concentration aggregate very rapidly (Bauer et al. 2000). The molten globule character of the oligomers observed here is perfectly in line with previous studies on other proteins (Booth et al. 1997; Kayed et al. 1999; McParland et al. 2000; Rochet and Lansbury 2000), demonstrating that aggregation is accelerated by ...

0027] In an embodiment of the present invention, the hydrocarbon startup stream comprises a stream that is recycled from the reactor outlet or from a fractionation section downstream of the oligomerisation reaction, or a stream that is obtained from an external source. In this embodiment, the hydrocarbon startup stream preferably is less reactive than the hydrocarbon feed stream containing the olefin. We prefer to use as a component of the hydrocarbon startup stream a stream that is less reactive but that is not foreign to the oligomerisation process, and/or which is readily acceptable to the process. Suitable streams are a recycle from the reactor outlet or a recycle from a fractionation section downstream of the oligomerisation reaction. The latter for instance may be a portion of the light byproduct stream in which saturates, which are typically coming in with the feed, are separated from the reactor effluent and are concentrated.

The value derived for Henrys Law constant H relates to the properties of the substance oligomerisation and alkylation reaction products of 2-phenylpropene and phenol [EC no. 700-960-7]. Vapour pressure (VP) and water solubility (WS) were obtained from tests with different samples of the substance (see CSR Chapter 1.3). The molecular weight was determined as average molecular weight of the different commercial products of the substance taking into account the percentage of the components in the products and their respective molecular weights. The 90th percentile of these data was taken as characteristic average molecular weight for the substance (average MW 298 g/mol). The constant H for the substance oligomerisation and reaction product … is calculated using the vapour pressure of 0.044 Pa and the water solubility of 4 mg C/L (= 0.0134 mol/m³), both at 21°C (see Chapter 1.3.).

For the B2RT-STOP-B2RT-2XMYC-vAChT donor construct, attempts were made to optimize the multimerization phenomenon by varying the quantity of substrate DNA and length of time of the Gibson reactions. For optimization of DNA quantity, Xho I/Pst I restriction digests for 20 independent clones resulting from 20-minute Gibson reactions using 200 (Figure S1A), 67 (Figure S1B), or 22 fmol (Figure S1C) of substrate DNA are shown. These restriction digests yielded constant bands of 5087, 1952, and 586 bp as well as variable bands from 642 bp (2XMYC) to 852 bp (7XMYC) in 42bp increments. The flexible linker GGSG was included between each MYC repeat to maximize the antigenic availability of the epitope tag and minimize the chances the tag alters the function of the vAChT protein. For each reaction condition, the MYC repeat number was quantitated as indicated for 200 (Figure S2A), 67 (Figure S2B), and 22 fmol (Figure S2C). Each reaction condition yielded at least one clone containing a 7XMYC repeat ...

Whats the best way to set up your grill and smoker? The secret is to have temperature control, and for grills, that almost always means using a 2-zone setup. For smokers, the secret is to get a small hot fire that makes clean blue smoke rather that billowy white smoke.
Soluble oligomeric aggregates of the amyloid-beta peptide (Abeta) have been implicated in the pathogenesis of Alzheimers disease (AD). Although the conformation adopted by Abeta within these aggregates is not known, a beta-hairpin conformation is known to be accessible to monomeric Abeta. Here we show that this beta-hairpin is a building block of toxic Abeta oligomers by engineering a double-cysteine mutant (called Abetacc) in which the beta-hairpin is stabilized by an intramolecular disulfide bond. Abeta(40)cc and Abeta(42)cc both spontaneously form stable oligomeric species with distinct molecular weights and secondary-structure content, but both are unable to convert into amyloid fibrils. Biochemical and biophysical experiments and assays with conformation-specific antibodies used to detect Abeta aggregates in vivo indicate that the wild-type oligomer structure is preserved and stabilized in Abetacc oligomers. Stable oligomers are expected to become highly toxic and, accordingly, we find ...
Oligomerization of membrane proteins has received intense research interest because of their importance in cellular signaling and the large pharmacological and clinical potential this offers. Fluorescence imaging methods are emerging as a valid tool to quantify membrane protein oligomerization at high spatial and temporal resolution. Here, we provide a detailed protocol for an image-based method to determine the number and oligomerization state of fluorescently labeled prototypical G-protein-coupled receptors (GPCRs) on the basis of small out-of-equilibrium fluctuations in fluorescence (i.e., molecular brightness) in single cells. The protocol provides a step-by-step procedure that includes instructions for (i) a flexible labeling strategy for the protein of interest (using fluorescent proteins, small self-labeling tags or bio-orthogonal labeling) and the appropriate controls, (ii) performing temporal and spatial brightness image acquisition on a confocal microscope and (iii) analyzing and ...
Chlamydia infections have an immense impact on public health and are associated with diverse disease manifestations including atherosclerosis, blindness, and sterility. The chlamydial developmental cycle is intrinsically linked with the ability of the organism to cause disease. The mechanisms that regulate the developmental cycle are poorly understood; however, transcription appears to play a governing role. An OmpR/PhoB subfamily response regulator termed ChxR exhibits expression patterns that indicate an important role during the developmental cycle. Previously, ChxR was demonstrated to interact with its own promoter and facilitate the transcriptional activation of the chxR gene. To begin to understand the functional role of ChxR, I identified the DNA sequence recognized by ChxR to identify its gene targets. Primarily using gel mobility shift assays, I determined that ChxR interacts with, and has differential affinity for six binding sites in the chxR promoter region. Using the DNA sequences ...
Six new R3 TACCrCl3 complexes, displaying branching on the second or third carbon of the ligand R group, were prepared for catalytic studies for ethylene oligomerisation and polymerisation. Five of the complexes made were activated with MAO and their reactivity towards ethylene, at ambient pressure and in a pressurised autoclave tested under various conditions. A number of the complexes were found to give good activities and selectivity for ethylene oligomerisation under optimum conditions. Chapter 2 discusses the design and synthesis of new R3 TACCrCl3 complexes displaying branching on the second or third carbon of the ligand R group. The complexes synthesised were characterised by paramagnetic NMR, magnetic moments, mass spectrometry, X-ray crystallography and elemental analysis. Chapter 3 explores the catalysis of an active selective ethylene oligomerisation R3TACCrCb complex which at optimal conditions shows higher activity for oligomerisation (trimerisation to l-hexene and higher oligomers) ...

Hinge region predictor (H-Predictor) predicts putative hinge regions involved in protein oligomerization via the domain-swapping mechanism. Domain swapping is an important mechanism for protein oligomerization, in which a fragment of a protein exchanges with a corresponding fragment of another like protein. The segment of polypeptide chain that links the swapped domain and the main protein is the hinge region. In most experimentally observed domain-swapped oligomers, the swapped domains correspond to one or several secondary structural elements from either the N- or C-termini. Only in some rare instances the swapped domains are positioned in the middle of the protein. The domain-swapped oligomeric structures are, therefore, mainly determined by the location and the properties of the hinge region.. Using a simple contact-based potential for enthalpy and graph theory- based estimation for entropy, H-Predictor quantifies for each residue the propensity as the hinge region. Physically, the ...
The photoreceptor cryptochrome 2 (CRY2) has become a powerful optogenetic tool that allows light-inducible manipulation of various signaling pathways and cellular processes in mammalian cells with high spatiotemporal precision and ease of application. However, it has also been shown that the behavior of CRY2 under blue light is complex, as the photoexcited CRY2 can both undergo homo-oligomerization and heterodimerization by binding to its dimerization partner CIB1. To better understand the light-induced CRY2 activities in mammalian cells, this article systematically characterizes CRY2 homo-oligomerization in different cellular compartments, as well as how CRY2 homo-oligomerization and heterodimerization activities affect each other. Quantitative analysis reveals that membrane-bound CRY2 has drastically enhanced oligomerization activity compared to that of its cytoplasmic form. While CRY2 homo-oligomerization and CRY2-CIB1 heterodimerization could happen concomitantly, the presence of certain ...

Cancer affects millions of people worldwide each year. Although effective treatments have been established for many forms of the disease, these therapies target the tumor suppressor p53, which is not involved in all cancers. It is thus critical to seek novel treatment methods that can affect cancers independent of p53. One group of homologous viruses have been found to code for a set of homologous proteins that selectively induce apoptosis in transformed cells in a p53 independent manner. This group includes the human homolog Torque Teno Virus (TTV). In order to explore TTV VP3s potential as a cancer therapeutic, several experiments concerning localization and multimerization were performed to evaluate and compare the apoptotic pathways of the highly characterized CAV Apoptin and TTV VP3.
The sole role of bradykinin (BK) as an inflammatory mediator is controversial, as recent data also support an anti-inflammatory role for BK in Alzheimers disease (AD).

The epidermal growth factor receptor (EGFR) is activated by dimerization, but activation also generates higher-order multimers, whose nature and function are poorly understood. We have characterized ligand-induced dimerization and multimerization of EGFR using single-molecule analysis, and show that multimerization can be blocked by mutations in a specific region of Domain IV of the extracellular module. These mutations reduce autophosphorylation of the C-terminal tail of EGFR and attenuate phosphorylation of phosphatidyl inositol 3-kinase, which is recruited by EGFR. The catalytic activity of EGFR is switched on through allosteric activation of one kinase domain by another, and we show that if this is restricted to dimers, then sites in the tail that are proximal to the kinase domain are phosphorylated in only one subunit. We propose a structural model for EGFR multimerization through self-association of ligand-bound dimers, in which the majority of kinase domains are activated cooperatively, ...
The extent to which Rhodopsin family G-protein-coupled receptors (GPCRs) form invariant oligomers is contentious. Recent single-molecule fluorescence imaging studies mostly argue against the existence of constitutive receptor dimers and instead suggest that GPCRs only dimerize transiently, if at all. However, whether or not even transient dimers exist is not always clear due to difficulties in unambiguously distinguishing genuine interactions from chance colocalizations, particularly with respect to short-lived events. Previous single-molecule studies have depended critically on calculations of chance colocalization rates and/or comparison with unfixed control proteins whose diffusional behavior may or may not differ from that of the test receptor. Here, we describe a single-molecule imaging assay that 1) utilizes comparisons with well-characterized control proteins, i.e., the monomer CD86 and the homodimer CD28, and 2) relies on cell fixation to limit artifacts arising from differences in the
