a member of the MAPKAPK family of protein kinases. Activated through phosphorylation by MAP kinases including ERK, p38-alpha, and MAPp38-beta In response to cellular stress and proinflammatory cytokines. Two alternately spliced transcript variants of this gene encoding distinct isoforms have been reported. Note: This description may include information from UniProtKB.
