Rsk1 is a member of a family of 90kDa ribosomal protein S6 kinases, which includes Rsk1, Rsk2 and Rsk3. These are broadly expressed serine/threonine protein kinases activated in response to mitogenic stimuli, including extracellular signal regulated protein kinases Erk1 and Erk2. Rsk1 is activated by MAPK in vitro and in vivo via phosphorylation. Active Rsks appear to play a major role in transcriptional regulation by translocating to the nucleus and phosphorylating c Fos and CREB. Function: Serine/threonine-protein kinase that acts downstream of ERK (MAPK1/ERK2 and MAPK3/ERK1) signaling and mediates mitogenic and stress-induced activation of the transcription factors CREB1, ETV1/ER81 and NR4A1/NUR77, regulates translation through RPS6 and EIF4B phosphorylation, and mediates cellular proliferation, survival, and differentiation by modulating mTOR signaling and repressing pro-apoptotic function of BAD and DAPK1. In fibroblast, is required for EGF-stimulated phosphorylation of CREB1, which results in the subsequent transcriptional activation of several immediate-early genes. In response to mitogenic stimulation (EGF and PMA), phosphorylates and activates NR4A1/NUR77 and ETV1/ER81 transcription factors and the cofactor CREBBP. Upon insulin-derived signal, acts indirectly on the transcription regulation of several genes by phosphorylating GSK3B at 'Ser-9' and inhibiting its activity. Phosphorylates RPS6 in response to serum or EGF via an mTOR-independent mechanism and promotes translation initiation by facilitating assembly of the preinitiation complex. In response to insulin, phosphorylates EIF4B, enhancing EIF4B affinity for the EIF3 complex and stimulating cap-dependent translation. Is involved in the mTOR nutrient-sensing pathway by directly phosphorylating TSC2 at 'Ser-1798', which potently inhibits TSC2 ability to suppress mTOR signaling, and mediates phosphorylation of RPTOR, which regulates mTORC1 activity and may promote rapamycin-sensitive signaling independently of the PI3K/AKT pathway. Mediates cell survival by phosphorylating the pro-apoptotic proteins BAD and DAPK1 and suppressing their pro-apoptotic function. Promotes the survival of hepatic stellate cells by phosphorylating CEBPB in response to the hepatotoxin carbon tetrachloride (CCl4). Is involved in cell cycle regulation by phosphorylating the CDK inhibitor CDKN1B, which promotes CDKN1B association with 14-3-3 proteins and prevents its translocation to the nucleus and inhibition of G1 progression. Subunit: Forms a complex with either MAPK1/ERK2 or MAPK3/ERK1 in quiescent cells. Transiently dissociates following mitogenic stimulation. Interacts with ETV1/ER81 and FGFR1. Subcellular Location: Nucleus. Cytoplasm. Post-translational modifications: Activated by phosphorylation at Ser-221 by PDPK1. Autophosphorylated on Ser-380, as part of the activation process. May be phosphorylated at Thr-359 and Ser-363 by MAPK1/ERK2 and MAPK3/ERK1. N-terminal myristoylation results in an activated kinase in the absence of added growth factors. Similarity: Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. S6 kinase subfamily. Contains 1 AGC-kinase C-terminal domain. Contains 2 protein kinase domains. Gene ID: 6195 p90RSK蛋白屬于廣泛表達的絲氨酸/蘇氨酸激酶。RSK家族包括RSK1、RSK2、RSK3和RSK4，它們的典型特征是含有兩個(gè)不同的功能性激酶結構域和羧基端ERKs(extracellular signal-regulated kinases)結合結構域。RSK激酶結構域內外的幾個(gè)位點(diǎn)包括Ser380、Thr359、Ser363和Thr573的磷酸化都對RSK的激酶活性激活非常重要。 RSK1-3可被MAPKs所磷酸化激活，也可以通過(guò)自身磷酸化激活，還可被一些生長(cháng)因子或神經(jīng)遞質(zhì)等誘導激活的PI3K信號通路所激活。RSK在被MAPK磷酸化激活時(shí)，是由Ras、Raf-1、MAP kinase kinase(MEK)和MAP kinase信號通路所介導。PI3K誘導的RSK1激活是由絲氨酸/蘇氨酸激酶mTOR介導的。 RSK1在葡萄糖穩態(tài)調控和細胞大小的調控中起重要作用。RSK可以磷酸化并調節轉錄因子c-fos和糖原合成酶激酶3(GSK3,glycogen synthase kinase 3)的活性。有報道RSK1可以和MAPK1、IκBα、TOB和TSC2等相互作用。RSK可以在有絲分裂信號刺激下會(huì )轉位到細胞核內。 |
