CC -!- FUNCTION: Serine/threonine-protein kinase that acts downstream of CC ERK (MAPK1/ERK2 and MAPK3/ERK1) signaling and mediates mitogenic CC and stress-induced activation of the transcription factors CREB1, CC ETV1/ER81 and NR4A1/NUR77, regulates translation through RPS6 and CC EIF4B phosphorylation, and mediates cellular proliferation, CC survival, and differentiation by modulating mTOR signaling and CC repressing pro-apoptotic function of BAD and DAPK1. In fibroblast, CC is required for EGF-stimulated phosphorylation of CREB1, which CC results in the subsequent transcriptional activation of several CC immediate-early genes. In response to mitogenic stimulation (EGF CC and PMA), phosphorylates and activates NR4A1/NUR77 and ETV1/ER81 CC transcription factors and the cofactor CREBBP. Upon insulin- CC derived signal, acts indirectly on the transcription regulation of CC several genes by phosphorylating GSK3B at 'Ser-9' and inhibiting CC its activity. Phosphorylates RPS6 in response to serum or EGF via CC an mTOR-independent mechanism and promotes translation initiation CC by facilitating assembly of the pre-initiation complex. In CC response to insulin, phosphorylates EIF4B, enhancing EIF4B CC affinity for the EIF3 complex and stimulating cap-dependent CC translation. Is involved in the mTOR nutrient-sensing pathway by CC directly phosphorylating TSC2 at 'Ser-1798', which potently CC inhibits TSC2 ability to suppress mTOR signaling, and mediates CC phosphorylation of RPTOR, which regulates mTORC1 activity and may CC promote rapamycin-sensitive signaling independently of the CC PI3K/AKT pathway. Mediates cell survival by phosphorylating the CC pro-apoptotic proteins BAD and DAPK1 and suppressing their pro- CC apoptotic function. Promotes the survival of hepatic stellate CC cells by phosphorylating CEBPB in response to the hepatotoxin CC carbon tetrachloride (CCl4). Mediates induction of hepatocyte CC prolifration by TGFA through phosphorylation of CEBPB (By CC similarity). Is involved in cell cycle regulation by CC phosphorylating the CDK inhibitor CDKN1B, which promotes CDKN1B CC association with 14-3-3 proteins and prevents its translocation to CC the nucleus and inhibition of G1 progression. Phosphorylates EPHA2 CC at 'Ser-897', the RPS6KA-EPHA2 signaling pathway controls cell CC migration (PubMed:26158630). {ECO:0000250|UniProtKB:P18653, CC ECO:0000250|UniProtKB:Q63531, ECO:0000269|PubMed:10679322, CC ECO:0000269|PubMed:11684016, ECO:0000269|PubMed:12213813, CC ECO:0000269|PubMed:15117958, ECO:0000269|PubMed:15342917, CC ECO:0000269|PubMed:16213824, ECO:0000269|PubMed:16223362, CC ECO:0000269|PubMed:16763566, ECO:0000269|PubMed:17360704, CC ECO:0000269|PubMed:18722121, ECO:0000269|PubMed:26158630, CC ECO:0000269|PubMed:9430688}.
