Western blot analysis of extracts from HeLa cells untreated or treated with PMA (200 uM, 30 min) using RPS6KA1 polyclonal antibody (Cat # PAB26704, lane1 and 2) and Rps6ka1 (phospho T348) polyclonal antibody (Cat # PAB5945, lane 3 and 4).
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.
