CC -!- FUNCTION: Serine/threonine-protein kinase that acts downstream of ERK CC (MAPK1/ERK2 and MAPK3/ERK1) signaling and mediates mitogenic and CC stress-induced activation of the transcription factors CREB1, ETV1/ER81 CC and NR4A1/NUR77, regulates translation through RPS6 and EIF4B CC phosphorylation, and mediates cellular proliferation, survival, and CC differentiation by modulating mTOR signaling and repressing pro- CC apoptotic function of BAD and DAPK1. In fibroblast, is required for CC EGF-stimulated phosphorylation of CREB1, which results in the CC subsequent transcriptional activation of several immediate-early genes. CC In response to mitogenic stimulation (EGF and PMA), phosphorylates and CC activates NR4A1/NUR77 and ETV1/ER81 transcription factors and the CC cofactor CREBBP. Upon insulin-derived signal, acts indirectly on the CC transcription regulation of several genes by phosphorylating GSK3B at CC 'Ser-9' and inhibiting its activity. Phosphorylates RPS6 in response to CC serum or EGF via an mTOR-independent mechanism and promotes translation CC initiation by facilitating assembly of the pre-initiation complex. In CC response to insulin, phosphorylates EIF4B, enhancing EIF4B affinity for CC the EIF3 complex and stimulating cap-dependent translation. Is involved CC in the mTOR nutrient-sensing pathway by directly phosphorylating TSC2 CC at 'Ser-1798', which potently inhibits TSC2 ability to suppress mTOR CC signaling, and mediates phosphorylation of RPTOR, which regulates CC mTORC1 activity and may promote rapamycin-sensitive signaling CC independently of the PI3K/AKT pathway. Mediates cell survival by CC phosphorylating the pro-apoptotic proteins BAD and DAPK1 and CC suppressing their pro-apoptotic function. Promotes the survival of CC hepatic stellate cells by phosphorylating CEBPB in response to the CC hepatotoxin carbon tetrachloride (CCl4). Mediates induction of CC hepatocyte prolifration by TGFA through phosphorylation of CEBPB (By CC similarity). Is involved in cell cycle regulation by phosphorylating CC the CDK inhibitor CDKN1B, which promotes CDKN1B association with 14-3-3 CC proteins and prevents its translocation to the nucleus and inhibition CC of G1 progression. Phosphorylates EPHA2 at 'Ser-897', the RPS6KA-EPHA2 CC signaling pathway controls cell migration (PubMed:26158630).
