Facts about MAP kinase-activated protein kinase 3.
MAPKAPK2 and MAPKAPK3, share the exact same function and substrate specificity, but MAPKAPK3 kinase activity and degree in protein expression are lower in comparison to MAPKAPK2. Phosphorylates HSP27/HSPB1, KRT18, KRT20, RCSD1, RPS6KA3, TAB3 and TTP/ZFP36.

Widely expressed, with a higher expression level observed in heart and skeletal muscle. No expression in brain. Expressed in the retinal pigment epithelium (PubMed:26744326).
Nucleus. Cytoplasm. Predominantly located in the nucleus, when activated it translocates to the cytoplasm.
