InnateDB Annotation
MAPKAPK2 phosphorylation is suppressed by lipomannan derived from virulent Mycobacterium tuberculosis (M.tb), resulting in the potent suppression of TNF biosynthesis and allowing M.tb to subvert host immunity and potentially to increase its virulence.

Entrez Gene
Summary This gene encodes a member of the Ser/Thr protein kinase family. This kinase is regulated through direct phosphorylation by p38 MAP kinase. In conjunction with p38 MAP kinase, this kinase is known to be involved in many cellular processes including stress and inflammatory responses, nuclear export, gene expression regulation and cell proliferation. Heat shock protein HSP27 was shown to be one of the substrates of this kinase in vivo. Two transcript variants encoding two different isoforms have been found for this gene.
