RPS6KA4 Antibody – Rabbit Polyclonal

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 CREB1 and ATF1. The encoded protein can also phosphorylate histone H3 to regulate certain inflammatory genes. Several transcript variants encoding different isoforms have been found for this gene.

MSK2: an AGC kinase of the RSK family. Has two kinase domains connected by a regulatory linker region. Phosphorylates H3 and HMG-14 in response to growth factors and cellular stress.
