P70-S6 Kinase 1 - Wikipedia
Ribosomal protein S6 kinase beta-1 (S6K1), also known as p70S6 kinase (p70S6K, p70-S6K), is an enzyme (specifically, a protein kinase) that in humans is encoded by the RPS6KB1 gene. [5] [6] It is a serine/threonine kinase that acts downstream of PIP3 and phosphoinositide-dependent kinase-1 in the PI3 kinase pathway. [7]
p70 S6 kinase as a therapeutic target in cancers: More than
Jun 1, 2022 · p70 S6 kinase (p70 S6K) is best known for its regulatory roles in protein synthesis and cell growth by phosphorylating its primary substrate, ribosomal protein S6, upon mitogen stimulation.
The mTOR-S6 kinase pathway promotes stress granule assembly
Mar 9, 2018 · Here we show that the mTOR effector kinases S6 kinase 1 (S6K1) and S6 kinase 2 (S6K2) localise to stress granules in human cells and are required for their assembly and maintenance after mild...
p70 S6 kinase and actin dynamics - PubMed Central (PMC)
p70 S6 kinase (p70S6K), a member of the AGC serine/threonine kinase family, was initially identified as a key player, together with its downstream effector S6, in the regulation of cellular growth and survival.
p70 Ribosomal protein S6 kinase (Rps6kb1): an update - PubMed
The Rps6kb1 gene encodes the 70 kDa ribosomal protein S6 kinase (p70S6K), which is a serine/threonine kinase regulated by phosphoinositide 3-kinase (PI3K)/mammalian target of rapamycin (mTOR) pathway. p70S6K plays a crucial role …
Up-Regulation of Phosphorylated/Activated p70 S6 Kinase and Its ...
The ribosomal S6 protein kinase p70 S6 kinase is known for its role in modulating cell-cycle progression, cell size, and cell survival. In response to mitogen stimulation, p70 S6 kinase activation up-regulates ribosomal biosynthesis and enhances the ...
p70S6 kinase regulates oligodendrocyte differentiation and is …
Feb 12, 2022 · We demonstrate that p70 ribosomal S6 kinase activity peaks in oligodendrocyte lineage cells at the time when they transition to myelinating oligodendrocytes during developmental myelination in the mouse spinal cord.
p70 Ribosomal protein S6 kinase - Journal of Clinical Pathology
The Rps6kb1 gene encodes the 70 kDa ribosomal protein S6 kinase (p70S6K), which is a serine/threonine kinase regulated by phosphoinositide 3-kinase (PI3K)/mammalian target of rapamycin (mTOR) pathway. p70S6K plays a crucial role …
Regulation of the p70 S6 Kinase by Phosphorylation in Vivo
We employed phospho-specific anti-peptide antibodies to examine the relative phosphorylation at several of these sites in wild type and various p70 mutants, in serum-deprived cells, and in response to activators and inhibitors of p70 S6 kinase activity.
Inhibition of mTOR complex 1/p70 S6 kinase signaling elevates
Jul 17, 2019 · We demonstrate that disruption of this signaling pathway with mTOR inhibitors, raptor knockdown or p70S6K inhibitors elevated PD-L1 levels in some lung and other cancer cell lines.
