External Ids for RPS6KA2 Gene
This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains 2 non-identical kinase catalytic domains and phosphorylates various substrates, including members of the mitogen-activated kinase (MAPK) signalling pathway. The activity of this protein has been implicated in controlling cell growth and differentiation. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.

GeneCards Summary for RPS6KA2 Gene
RPS6KA2 (Ribosomal Protein S6 Kinase, 90kDa, Polypeptide 2) is a Protein Coding gene. Diseases associated with RPS6KA2 include coffin-lowry syndrome. Among its related pathways are Signaling by FGFR and Signaling by FGFR. GO annotations related to this gene include protein serine/threonine kinase activity and ribosomal protein S6 kinase activity. An important paralog of this gene is MKNK2.
UniProtKB/Swiss-Prot for RPS6KA2 Gene
Serine/threonine-protein kinase that acts downstream of ERK (MAPK1/ERK2 and MAPK3/ERK1) signaling and mediates mitogenic and stress-induced activation of transcription factors, regulates translation, and mediates cellular proliferation, survival, and differentiation. May function as tumor suppressor in epithelial ovarian cancer cells.
p90 ribosomal S6 kinases (RSKs) are a family of protein serine/threonine kinases that regulate diverse cellular processes such as cell growth, motility, survival and proliferation. There are four isoforms of this enzyme; RSK1-4, which are directly activated by ERK1/2 in response to growth factors, many polypeptide hormones, neurotransmitters and chemokines. p90 RSKs phosphorylate numerous cytosolic and nuclear targets and act as downstream effectors of the ERK/MAPK signaling cascade. They are expressed ubiquitously in human tissues and exist in multiple subcellular compartments. Abberant activation of p90 RSKs has been linked to many human diseases, including breast and prostate cancers.
