Rabbit Anti-Phospho-RSK3 (Thr356 + Ser72)/FITC Conjugated antibody
background:
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. [provided by RefSeq, Jul 2008].
Function:
Serine/threonine-protein kinase that acts downstream ofERK (MAPK1/ERK2 and MAPK3/ERK1) signaling and mediates mitogenicand stress-induced activation of transcription factors, regulatestranslation, and mediates cellular proliferation, survival, anddifferentiation. May function as tumor suppressor in epithelialovarian cancer cells.
Subunit:
Forms a complex with either MAPK1/ERK2 or MAPK3/ERK1 inquiescent cells. Transiently dissociates following mitogenicstimulation.
Subcellular Location:
Nucleus. Cytoplasm.
Tissue Specificity:
Widely expressed with higher expression inlung, skeletal muscle, brain, uterus, ovary, thyroid and prostate.
Post-translational modifications:
Activated by phosphorylation at Ser-218 by PDPK1.Autophosphorylated on Ser-377, as part of the activation process.May be phosphorylated at Thr-356 and Ser-72 by MAPK1/ERK2 andMAPK3/ERK1.
N-terminal myristoylation results in an activated kinase inthe absence of added growth factors.
Similarity:
Belongs to the protein kinase superfamily. AGC Ser/Thrprotein kinase family. S6 kinase subfamily.
Contains 1 AGSLCkinase SLCterminal domain.
Contains 2 protein kinase domains.
