Protein Structure
UniProt Annotation
Function Protein phosphatase that mediates dephosphorylation of proteins phosphorylated on Tyr and Ser/Thr residues. In vitro, it can dephosphorylate p44-ERK1 (MAPK3) but not p54 SAPK-beta (MAPK10) in vitro. Able to enhance activation of JNK and p38 (MAPK14). {ECO:0000269PubMed:15147733, ECO:0000269PubMed:15201283}.
Subcellular Localization Cytoplasm, cytosol. Nucleus. Note=Mainly cytosolic. Also nuclear.
Disease Associations
Tissue Specificity Widely expressed. Highly expressed in spleen, prostate, colon, adrenal gland, mammary gland, thyroid and trachea. Expressed at lower level in uterus, small intestine, bladder, bone marrow, brain, spinal cord and stomach. {ECO:0000269PubMed:15147733, ECO:0000269PubMed:15201283}.
