In the presence of nutrients, mTORC1 is activated and promotes cell growth, including protein synthesis and energy storage. (springer.com)
The delicate equilibrium between protein synthesis and protein degradation is crucial for healthy cell function and dysregulation of protein homoeostasis is a common occurrence in human disease. (bvsalud.org)
We speculated that the defect of protein synthesis attenuated expression of other exoglucanases or glucan synthesis-related proteins, and then induced release of Xog1p to the cell wall. (ncl.edu.tw)
C. albicans Hom6p thus had an effect on cell survival and cell adhesion by maintaining protein synthesis and cell wall function. (ncl.edu.tw)

Mutant Ras is a driver both in tumor initiation and tumor maintenance [ 5 ] [ 7 ] . (encyclopedia.pub)
The mutant proteins often retain some of their capabilities but are no longer sensitive to the controls that regulate the normal form of the protein. (cancerquest.org)
Furthermore, p75 mutant neurons display reduced levels of activated RhoA compared with wild-type counterparts, consistent with the enhanced filopodial lengths observed on mutant growth cones. (jneurosci.org)
Genome-wide single-nucleotide polymorphism analysis in juvenile myelomonocytic leukemia identifies uniparental disomy surrounding the NF1 locus in cases associated with neurofibromatosis but not in cases with mutant RAS or PTPN11. (lu.se)

other specificity is tiny gene activity and distribution browser through the kinase of the R-RasGAP complex ileal to suitable or through the functionality of RhoA. (evakoch.com)
typically, reticulum of deaminase by kinase extends the download of primary transporters by docking the brain of RhoA. (evakoch.com)
Furthermore, p75 NTR regulates RhoA activity to mediate filopodial dynamics. (jneurosci.org)
These observations suggest that neurotrophins regulate filopodial dynamics by depressing the activation of RhoA that occurs through p75 NTR signaling. (jneurosci.org)
1999 ) provided evidence that p75 NTR can regulate axon extension by signaling through the RhoA pathway, such that the unbound state of p75 NTR activates RhoA, whereas neurotrophin binding to p75 NTR terminates this mode of RhoA activation. (jneurosci.org)
Growth cone behaviors were not investigated in previous studies, and it is unknown whether neurotrophin-p75 NTR interactions regulate RhoA activity in growth cones. (jneurosci.org)

PIP3 then recruits Akt to the plasma membrane, where it is activated by phosphorylation. (ebiwinner.com)
The protein encoded by this gene is prenylated at its C-terminus, and localizes to the cytoplasm and plasma membrane. (cancerindex.org)
It was reported that SM could form cluster in outer leaflet of the membrane, where juxtapose inner leaflet region could recruit phosphatidylinositol-5-kinase to form PIP 2 . (sphingolipidclub.com)
Membrane embedded proteins are functionally regulated by the lipid composition of the surrounding bilayer. (sphingolipidclub.com)
Here we uncover structural motifs required for ceramide interaction with the four membrane spanning Lysosome Associated Protein Transmembrane 4B (LAPTM4B). (sphingolipidclub.com)

The experiments showed that different amino acids in the active site of the Rab protein are involved when the GEFs mediate the release of the GDP during the activation process. (elifesciences.org)
For example, the amino acid glutamine is involved when the Listeria GEF and one of the human GEFs activate the protein, whereas a different amino acid-aspartate-is involved when one of the other human GEFs is responsible for the activation. (elifesciences.org)

In this manner the neurons strike a "balance" that allows for neurons to become activated and convey discrete synaptic signals, while preventing excessive excitation. (frontiersin.org)
To further analyze neurotrophin regulation of growth cone behaviors, we examined the role of p75 NTR in regulating filopodial dynamics in peripheral and CNS neurons. (jneurosci.org)

The 70 or so members of the Rab subfamily of proteins perform a wide range of important tasks inside cells. (elifesciences.org)
Neurofibromin loss potentially hyperactivates classic Ras (H-Ras, N-Ras, K-Ras), M-Ras, and R-Ras (R-Ras, R-Ras2/TC21) subfamily proteins. (biomedcentral.com)

This download is the types and cells led from a human assembly target content soccer methylated alongside the set of two interaction localizing enzyme proteins in New Zealand. (evakoch.com)

MiRNAs, short (18-24 nucleotides) non-coding RNAs, are derived from long transcripts pri-miRNAs and pre-miRNAs [ 26 - 30 ].By targeting 3' untranslated regions (3'UTRs) of cognate mRNAs, miRNAs post-transcriptionally regulate gene expression and induce translational repression [ 29 , 30 ]. (intechopen.com)

In the PARK2-dependent pathway, PINK1 activates PARK2 to target many mitochondrial proteins, including NDP52, OPTN and p62, and it combines with LC3 to deliver damaged mitochondria to autophagosomes [ 15 ]. (ijbs.com)

EMT is an embryologically conserved genetic program by which epithelial cells down regulate intercellular tight junctions, loose polarity, express mesenchymal markers, and manifest a migratory phenotype [ 1 ]. (intechopen.com)

Furthermore, Rab1 switch II glutamine mutants refractory to activation by DrrA can be activated by TRAPP, showing that a single Rab can be activated by more than one mechanistically distinct GDP-release pathway. (elifesciences.org)

Additionally, Akt promotes cell survival by inhibiting pro-apoptotic factors and activating anti-apoptotic factors. (ebiwinner.com)

They regulate signalling though inhibition of phosphatases and induction of the activity of Stress Activated Protein Kinases, which themselves modulate feedbacks to insulin signalling and FOXO. (biomedcentral.com)

Adenosine triphosphate (ATP) at millimolar levels has recently been implicated in the solubilization of cellular proteins. (waseda.jp)

Depletion of S100A10 from RAS-transformed cells resulted in a loss of both cellular plasmin generation and invasiveness. (oncotarget.com)
