The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel.

The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.

An intracellular signaling system involving the MAP kinase cascades (three-membered protein kinase cascades). Various upstream activators, which act in response to extracellular stimuli, trigger the cascades by activating the first member of a cascade, MAP KINASE KINASE KINASES; (MAPKKKs).

The highly conserved beta-hairpin of the paired DNA-binding domain is required for assembly of Pax-Ets ternary complexes. (1/340)

Pax family transcription factors bind DNA through the paired domain. This domain, which is comprised of two helix-turn-helix motifs and a beta-hairpin structure, is a target of mutations in congenital disorders of mice and humans. Previously, we showed that Pax-5 (B-cell-specific activator protein) recruits proteins of the Ets proto-oncogene family to bind a composite DNA site that is essential for efficient transcription of the early-B-cell-specific mb-1 promoter. Here, evidence is provided for specific interactions between Ets-1 and the amino-terminal subdomains of Pax proteins. By tethering deletion fragments of Pax-5 to a heterologous DNA-binding domain, we show that 73 amino acids (amino acids 12 to 84) of its amino-terminal subdomain can recruit the ETS domain of Ets-1 to bind the composite site. Furthermore, an amino acid (Gln22) within the highly conserved beta-hairpin motif of Pax-5 is essential for efficient recruitment of Ets-1. The ability to recruit Ets proteins to bind DNA is a shared property of Pax proteins, as demonstrated by cooperative DNA binding of Ets-1 with sequences derived from the paired domains of Pax-2 and Pax-3. The strict conservation of sequences required for recruitment of Ets proteins suggests that Pax-Ets interactions are important for regulating transcription in diverse tissues during cellular differentiation.  (+info)

Distinct factors regulate the murine RAG-2 promoter in B- and T-cell lines. (2/340)

The recombination activating genes RAG-1 and RAG-2 are expressed in a lymphoid-cell-specific and developmentally regulated fashion. To understand the transcriptional basis for this regulation, we have cloned and characterized the murine RAG-2 promoter. The promoter was lymphoid cell specific, showing activity in various B- and T-cell lines but little activity in nonlymphoid cells. To our surprise, however, the promoter was regulated differently in B and T cells. Using nuclear extracts from B-cell lines, we found that the B-cell-specific transcription factor BSAP (Pax-5) could bind to a conserved sequence critical for promoter activity. BSAP activated the promoter in transfected cells, and the BSAP site was occupied in a tissue-specific manner in vivo. An overlapping DNA sequence binding to a distinct factor was necessary for promoter activity in T cells. Full promoter activity in T cells was also dependent on a more distal DNA sequence whose disruption had no effect on B-cell activity. The unexpected finding that a B-cell-specific factor regulates the RAG-2 promoter may explain some of the recently observed differences in the regulation of RAG transcription between B and T cells.  (+info)

B cell-specific activator protein prevents two activator factors from binding to the immunoglobulin J chain promoter until the antigen-driven stages of B cell development. (3/340)

The immunoglobulin J chain gene is inducibly transcribed in mature B cells upon antigen recognition and a signal from interleukin-2 (IL-2). B cell-specific activator protein (BSAP), a transcription factor that silences J chain transcription, has been identified as a nuclear target of the IL-2 signal. The levels of BSAP progressively decrease in response to IL-2 and this change correlates with the differentiation of B cells into antibody secreting plasma cells. Here we report the binding of the upstream stimulatory factor (USF) to an E-box motif immediately upstream from the BSAP site on the J chain promoter. Mutations in the USF binding motif significantly decrease J chain promoter activity in J chain expressing B cell lines. We also show that a functional relationship exists between USF and a second J chain positive-regulating factor, B-MEF2, using co-immunoprecipitation assays and transfections. Finally, we provide evidence that the binding of BSAP prevents USF and B-MEF2 from interacting with the J chain promoter during the antigen-independent stages of B cell development. It is not until the levels of BSAP decrease during the antigen-driven stages of B cell development that both USF and B-MEF2 are able to bind to their respective promoter elements and activate J chain transcription.  (+info)

Pax2/5 and Pax6 subdivide the early neural tube into three domains. (4/340)

The nested expression patterns of the paired-box containing transcription factors Pax2/5 and Pax6 demarcate the midbrain and forebrain primordium at the neural plate stage. We demonstrate that, in Pax2/5 deficient mice, the mesencephalon/metencephalon primordium is completely missing, resulting in a fusion of the forebrain to the hindbrain. Morphologically, in the alar plate the deletion is characterized by the substitution of the tectum (dorsal midbrain) and cerebellum (dorsal metencephalon) by the caudal diencephalon and in the basal plate by the replacement of the midbrain tegmentum by the ventral metencephalon (pons). Molecularly, the loss of the tectum is demonstrated by an expanded expression of Pax6, (the molecular determinant of posterior commissure), and a rostral shift of the territory of expression of Gbx2 and Otp (markers for the pons), towards the caudal diencephalon. Our results suggest that an intact territory of expression of Pax2/5 in the neural plate, nested between the rostral and caudal territories of expression of Pax6, is necessary for defining the midbrain vesicle.  (+info)

Coordinate regulation of B cell differentiation by the transcription factors EBF and E2A. (5/340)

The transcription factors EBF and E2A are required at a similar step in early B cell differentiation. EBF and E2A synergistically upregulate transcription of endogenous B cell-specific genes in a non-B cell line. Here, we examine a genetic collaboration between these factors in regulating B lymphopoiesis. We find that Ebf+/- E2a+/- mice display a marked defect in pro-B cell differentiation at a stage later than observed in the single homozygous mutant mice. Pro-B cells from Ebf+/- E2a+/- mice show reduced expression of lymphoid-specific transcripts, including Pax5, Rag1, Rag2, and mb-1. We also show that EBF directly binds and activates the Pax5 promoter. Together, these data show collaboration between EBF and E2A and provide insight into the hierarchy of transcription factors that regulate B lymphocyte differentiation.  (+info)

AML1 (CBFalpha2) cooperates with B cell-specific activating protein (BSAP/PAX5) in activation of the B cell-specific BLK gene promoter. (6/340)

AML1 plays a critical role during hematopoiesis and chromosomal translocations involving AML1 are commonly associated with different forms of leukemia, including pre-B acute lymphoblastic leukemia. To understand the function of AML1 during B cell differentiation, we analyzed regulatory regions of B cell-specific genes for potential AML1-binding sites and have identified a putative AML1-binding site in the promoter of the B cell-specific tyrosine kinase gene, blk. Gel mobility shift assays and transient transfection assays demonstrate that AML1 binds specifically to this site in the blk promoter and this binding site is important for blk promoter activity. Furthermore, in vitro binding analysis revealed that the AML1 runt DNA-binding domain physically interacts with the paired DNA-binding domain of BSAP, a B cell-specific transcription factor. BSAP has been shown previously to be important for B cell-specific regulation of the blk gene. Physical interaction of AML1 with BSAP correlates with functional cooperativity in transfection studies where AML1 and BSAP synergistically activate blk promoter transcription by more than 50-fold. These results demonstrate physical and functional interactions between AML1 and BSAP and suggest that AML1 is an important factor for regulating a critical B cell-specific gene, blk.  (+info)

FGF8 can activate Gbx2 and transform regions of the rostral mouse brain into a hindbrain fate. (7/340)

The mid/hindbrain junction region, which expresses Fgf8, can act as an organizer to transform caudal forebrain or hindbrain tissue into midbrain or cerebellar structures, respectively. FGF8-soaked beads placed in the chick forebrain can similarly induce ectopic expression of mid/hindbrain genes and development of midbrain structures (Crossley, P. H., Martinez, S. and Martin, G. R. (1996) Nature 380, 66-68). In contrast, ectopic expression of Fgf8a in the mouse midbrain and caudal forebrain using a Wnt1 regulatory element produced no apparent patterning defects in the embryos examined (Lee, S. M., Danielian, P. S., Fritzsch, B. and McMahon, A. P. (1997) Development 124, 959-969). We show here that FGF8b-soaked beads can not only induce expression of the mid/hindbrain genes En1, En2 and Pax5 in mouse embryonic day 9.5 (E9.5) caudal forebrain explants, but also can induce the hindbrain gene Gbx2 and alter the expression of Wnt1 in both midbrain and caudal forebrain explants. We also show that FGF8b-soaked beads can repress Otx2 in midbrain explants. Furthermore, Wnt1-Fgf8b transgenic embryos in which the same Wnt1 regulatory element is used to express Fgf8b, have ectopic expression of En1, En2, Pax5 and Gbx2 in the dorsal hindbrain and spinal cord at E10.5, as well as exencephaly and abnormal spinal cord morphology. More strikingly, Fgf8b expression in more rostral brain regions appears to transform the midbrain and caudal forebrain into an anterior hindbrain fate through expansion of the Gbx2 domain and repression of Otx2 as early as the 7-somite stage. These findings suggest that normal Fgf8 expression in the anterior hindbrain not only functions to maintain development of the entire mid/hindbrain by regulating genes like En1, En2 and Pax5, but also might function to maintain a metencephalic identity by regulating Gbx2 and Otx2 expression.  (+info)

Early B cell factor is an activator of the B lymphoid kinase promoter in early B cell development. (8/340)

Early B cell factor (EBF) is a transcription factor suggested to be involved in the transcriptional control of several B cell restricted genes. EBF is also essential for B lymphocyte development because mice carrying a homologous disruption of the EBF gene lack mature B lymphocytes. This makes the identification of genetic targets for EBF important for the understanding of early B cell development. Examination of the nucleotide sequence of the B lymphoid kinase (Blk) promoter suggested the presence of an EBF binding site, and in vivo footprinting analysis showed that the site was protected from methylation in a pre-B cell line. EMSA indicated that recombinant and cellular EBF interact physically with this site; furthermore, transient transfections indicated that ectopic expression of EBF in nonlymphoid HeLa cells activate a Blk promoter-controlled reporter construct 9-fold. The defined EBF binding site was also important for the function of the Blk promoter in pre-B cells, because transient transfections of a reporter construct under the control of an EBF site-mutated Blk promoter displayed only 20-30% of the activity of the wild-type promoter. Furthermore, transient transfections in HeLa cells proposed that EBF and B cell-specific activator protein were able to cooperate in the activation of a Blk promoter-controlled reporter construct. These data indicate that EBF plays an important role in the regulation of the Blk promoter in early B cell development and that EBF and BSAP are capable to act in cooperation to induce a target gene.  (+info)

Title: Coordinated Expression of Pax-5 and FAK1 in Metastasis. VOLUME: 11 ISSUE: 7. Author(s):Nicolas Crapoulet, Pierre OBrien, Rodney J. Ouellette and Gilles A. Robichaud. Affiliation:Universite de Moncton, Moncton, NB, Canada, E1A 3E9.. Keywords:Cancer, cell signaling, FAK1, focal adhesion, metastasis, Pax-5, B lymphopoiesis, cell differentiation, homeostasis, leukemia. Abstract: The Pax-5 gene encodes a B-cell-specific activator protein (BSAP) that plays a key role in B lymphocyte differentiation and embryogenesis. The deregulation of this transcription factor is also linked to B cell malignancies and recently to other cancers. More specifically, the downstream effects of Pax-5 promote cell-cell interactions and mediate the activation of adhesion genes which result in an epithelial phenotypic behavior of human carcinoma cells. To gain a better understanding of Pax-5-mediated gene regulation, we studied available gene expression data in depth and identified several Pax-5 downstream targets. ...
TY - JOUR. T1 - NF-HB (BSAP) is a repressor of the murine immunoglobulin heavy-chain 3′α enhancer at early stages of B-cell differentiation. AU - Singh, Mallika. AU - Birshtein, Barbara K.. PY - 1993/6. Y1 - 1993/6. N2 - We have identified a nuclear factor expressed in pro-B-, pre-B-, and B-cell lines that binds to two sites within the murine immunoglobulin heavy-chain (IgH) 3′α enhancer (3′αE). These sites were defined by oligonucleotide competition in an electrophoretic mobility shift assay (EMSA) and methylation interference footprinting. The 3′αE-binding factor is indistinguishable from NF-HB (B-lineage-specific nuclear factor that binds to the IgH gene) and the B-lineage-specific transcription factor BSAP by several criteria, including similar cell type distribution of binding activity, cross-competition of binding sites in EMSA, similar protein size as demonstrated by UV cross-linking, and sequence identity of one of the 3′αE-binding sites with a BSAP-binding site within the ...
The cerebral cortex forms by the orderly migration and subsequent differentiation of neuronal precursors generated in the proliferative ventricular zone. We studied the role of the transcription factor Pax-6, which is expressed in the ventricular zone, in cortical development. Embryos homozygous for a mutation of Pax-6 (Small eye; Sey) had abnormalities suggesting defective migration of late-born cortical precursors. When late-born Sey/Sey precursors were transplanted into wild-type embryonic rat cortex, they showed similar integrative, migrational and differentiative abilities to those of transplanted wild-type mouse precursors. These results suggest that postmitotic cortical cells do not need Pax-6 to acquire the capacity to migrate and differentiate, but that Pax-6 generates a cortical environment that permits later-born precursors to express their full developmental potential.. ...

Orexins or hypocretins are neurotransmitters produced by a small population of neurons in the lateral hypothalamus. This family of peptides modulates sleep‑wake cycle, arousal and feeding behaviors; however, the mechanisms regulating their expression remain to be fully elucidated. There is an interest in defining the key molecular elements in orexin regulation, as these may serve to identify targets for generating novel therapies for sleep disorders, obesity and addiction. Our previous studies showed that the expression of orexin was decreased in mice carrying null‑mutations of the transcription factor early B‑cell factor 2 (ebf2) and that the promoter region of the prepro‑orexin (Hcrt) gene contained two putative ebf‑binding sites, termed olf‑1 sites ...

Signaling through the Notch1 receptor is essential for T cell development in the thymus. Stromal OP9 cells ectopically expressing the Notch ligand Delta-like1 mimic the thymic environment by inducing hemopoietic stem cells to undergo in vitro T cell development. Notch1 is also expressed on Pax5-/- pro-B cells, which are clonable lymphoid progenitors with a latent myeloid potential. In this study, we demonstrate that Pax5-/- progenitors efficiently differentiate in vitro into CD4+CD8+ alphabeta and gammadelta T cells upon coculture with OP9-Delta-like1 cells. In vitro T cell development of Pax5-/- progenitors strictly depends on Notch1 function and progresses through normal developmental stages by expressing T cell markers and rearranging TCRbeta, gamma, and delta loci in the correct temporal sequence. Notch-stimulated Pax5-/- progenitors efficiently down-regulate the expression of B cell-specific genes, consistent with a role of Notch1 in preventing B lymphopoiesis in the thymus. At the same ...
Deoxyuridine (dU) is a pyrimidine deoxyribonucleoside, and a derivative of the nucleoside uridine, with the only difference being that, in dU, a hydrogen (-H) group is substituted for uridine s OH group located at the 2 -position of the ribose. dU is generated in cellular DNA as a deamination product of dC (deoxycytidine), with the deamination process catalyzed by the enzyme AID (activation-induced cytidine deaminase) (1). AID is a B cell-specific gene that is necessary for antibody gene diversification via class-switch recombination and somatic hypermutation (2, 3). The dC-to-dU conversion(s) by AID occurs in the IgG locus, with various gene diversification pathways arising from the different DNA repair mechanisms used by B-cells to repair the dU lesion (1).. dC-to-dU conversion via cytidine deamination is also implicated in innate immunity to retroviruses. Here deamination of dC is mediated by the enzyme APOBEC3G, which is present in T cells, acting on the first (minus) strand cDNA of ...
In the human paired box-containing (PAX) gene family, only two members, PAX-3 and PAX-6, which are associated with Waardenburgs syndrome and aniridia, respectively have been mapped to human chromosomes. We have now isolated cosmids for six additional human PAX genes (PAX-1,-2,-5,-7,-8,-9) and a polymerase chain reaction fragment for PAX-4. PAX-9 is a novel family member which is closely related in its paired domain to PAX-1. The chromosomal location of all cloned PAX genes was determined by analysis of somatic cell hybrids and (except PAX-4) by fluorescence in situ hybridization to metaphase chromosomes. PAX-1 and PAX-7 map to chromosomal regions containing previously assigned disease loci.

TY - JOUR. T1 - SUMOylation of Blimp-1 is critical for plasma cell differentiation. AU - Ying, Hsia Yuan. AU - Su, Shin Tang. AU - Hsu, Pang Hung. AU - Chang, Che Chang. AU - Lin, I. Ying. AU - Tseng, Yu Hsuan. AU - Tsai, Ming Daw. AU - Shih, Hsiu Ming. AU - Lin, Kuo I.. PY - 2012/7. Y1 - 2012/7. N2 - Transcriptional repressor B lymphocyte-induced maturation protein-1 (Blimp-1) is a master regulator of plasma cell differentiation. Here we show that Blimp-1 is covalently modified by SUMO1 at lysine 816, a modification mediated by SUMO E3 ligase PIAS1. Mutation of Blimp-1 lysine 816 reduces transcriptional repression-correlating with a reduced interaction with a histone deacetylase, HDAC2-and impairs differentiation of antibody-secreting cells. Thus, the SUMO pathway critically regulates Blimp-1 function during plasma cell differentiation..
