Rsk-1 (phospho Thr573) Rabbit Polyclonal Antibody

Ribosomal protein S6 kinase A1 (RPS6KA1) Homo sapiens This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains 2 nonidentical 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. [provided by RefSeq, Jul 2008], catalytic activity:ATP + a protein = ADP + a phosphoprotein., caution:The sequence shown here is derived from an Ensembl automatic analysis pipeline and should be considered as preliminary data., cofactor:Magnesium., enzyme regulation:Activated by multiple phosphorylations on threonine and serine residues., function:Serine/threonine kinase that may play a role in mediating the growth-factor and stress induced activation of the transcription factor CREB., PTM:Autophosphorylated on Ser-380, as part of the activation process., similarity:Belongs to the protein kinase superfamily., similarity:Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. S6 kinase subfamily., similarity:Contains 1 AGC-kinase C-terminal domain., similarity:Contains 2 protein kinase domains., subunit:Forms a complex with either ERK1 or ERK2 in quiescent cells. Transiently dissociates following mitogenic stimulation.
