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 (PubMed:10679322, PubMed:12213813, PubMed:15117958, PubMed:16223362, PubMed:17360704, PubMed:18722121, PubMed:26158630, PubMed:35772404, PubMed:9430688). In fibroblast, is required for EGF-stimulated phosphorylation of CREB1, which results in the subsequent transcriptional activation of several immediate-early genes (PubMed:18508509, PubMed:18813292). In response to mitogenic stimulation (EGF and PMA), phosphorylates and activates NR4A1/NUR77 and ETV1/ER81 transcription factors and the cofactor CREBBP (PubMed:12213813, PubMed:16223362). Upon insulin-derived signal, acts indirectly on the transcription regulation of several genes by phosphorylating GSK3B at 'Ser-9' and inhibiting its activity (PubMed:18508509, PubMed:18813292). Phosphorylates RPS6 in response to serum or EGF via an mTOR-independent mechanism and promotes translation initiation by facilitating assembly of the pre-initiation complex (PubMed:17360704). In response to insulin, phosphorylates EIF4B, enhancing EIF4B affinity for the EIF3 complex and stimulating cap-dependent translation (PubMed:16763566). 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 (PubMed:15342917). Also involved in feedback regulation of mTORC1 and mTORC2 by phosphorylating DEPTOR (PubMed:22017876). Mediates cell survival by phosphorylating the pro-apoptotic proteins BAD and DAPK1 and suppressing their pro-apoptotic function (PubMed:10679322, PubMed:16213824). Promotes the survival of hepatic stellate cells by phosphorylating CEBPB in response to the hepatotoxin carbon tetrachloride (CCl4) (PubMed:11684016). Mediates induction of hepatocyte prolifration by TGFA through phosphorylation of CEBPB (PubMed:18508509, PubMed:18813292). 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 (PubMed:18508509, PubMed:18813292). Phosphorylates EPHA2 at 'Ser-897', the RPS6KA-EPHA2 signaling pathway controls cell migration (PubMed:26158630). In response to mTORC1 activation, phosphorylates EIF4B at 'Ser-406' and 'Ser-422' which stimulates bicarbonate cotransporter SLC4A7 mRNA translation, increasing SLC4A7 protein abundance and function (PubMed:35772404). (Microbial infection) Promotes the late transcription and translation of viral lytic genes during Kaposi's sarcoma-associated herpesvirus/HHV-8 infection, when constitutively activated.

RSK1 also known as p90 ribosomal S6 kinase 1 or p90RSK is a serine/threonine kinase with an approximate mass of 90 kDa. It belongs to the family of proteins that integrate signals from various extracellular stimuli. This kinase is expressed in diverse tissues including brain lung liver and skeletal muscle. At the molecular level RSK1 phosphorylates various target proteins that are involved in regulating cellular growth and survival. Its activity is regulated by phosphorylation events that occur at specific sites such as Serine 238 (E238 in some literature) which are critical for its function.
RSK1 plays a fundamental role in cell proliferation and differentiation in the context of the p90 protein weight. It is an important component of the mitogen-activated protein kinase (MAPK) signaling pathway and forms part of multi-protein complexes that facilitate its activation and function. RSK1 influences various biological processes by phosphorylating transcription factors histone proteins and other kinases thereby regulating gene expression and protein synthesis. These actions highlight its influence in maintaining cellular homeostasis.
RSK1 p90 interacts significantly with the MAPK/ERK and PI3K/AKT pathways. It acts downstream of ERK where it receives activating signals that enable it to phosphorylate substrates within the cell. This role supports its interaction with proteins like Akt and mTOR which are critical mediators of cell growth signals. The interplay between these pathways enables cells to respond to growth factors and stress contributing to the regulation of development and metabolism.
RSK1 is implicated in the progression of cancer and neurological disorders. In cancer abnormal RSK1 signaling can lead to unchecked cell growth and survival where it often interfaces with proteins such as C-RAF and BCL-2 to promote oncogenic pathways. In neurological disorders RSK1 influences pathways that regulate neuron survival and plasticity connecting it to proteins like CREB. Understanding RSK1's role in these conditions can provide insight into targeted therapies that may mitigate these diseases.
