MKP5, active

Dual specificity protein phosphatases inactivate their target kinases by dephosphorylating both the
phosphoserine/threonine and phosphotyrosine residues. They negatively regulate members of the MAPK superfamily
(MAPK/ERK, SAPK/JNK, p38), which is associated with cellular proliferation and differentiation. Different members ofthis family of dual specificity phosphatases show distinct substrate specificities for MAPKs, different tissue
distribution and subcellular localization, and different modes of inducibility of their expression by extracellular
stimuli. This gene product binds to and inactivates p38 and SAPK/JNK, but not MAPK/ERK. Its subcellular localization
is unique; it is evenly distributed in both the cytoplasm and the nucleus. This gene is widely expressed in various
tissues and organs, and its expression is elevated by stress stimuli. Three transcript variants encoding two different
isoforms have been found for this gene.

N-terminal 6His-tagged, recombinant, human MKP5, amino acids 320-end, expressed in E. coli.
