Background Information

RSK3, also named as RPS6KA2, belongs to the protein kinase superfamily. RSK3 is a 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. In addition RSK3 may function as tumor suppressor in epithelial ovarian cancer cells(Uniprot). The molecular weight of RSK3 is 83 kDa.
