Contents
Subfamilies
ACP2
ACP2 is a protein phosphatase subfamily that usually has multiple copies per genome. Human has three copies with different tissue specificity. It is found in holozoa, ameobozoa, and some protists.
MINPP1
MINPP1 is a non-protein phosphatase found in a broad of eukaryotes, including most metazoan and amoebazoan. Known substrates include InsP6 and 2,3-BPG.
PXYLP1 (ACPL2)
PXYLP1 dephosphorylates xylose, a sugar, in the glycosaminoglycan-protein linkage region of proteoglycans [1]. It is widely found in bilateria.
PPIP5K
PPIP5K has a pseudophosphatase domain which bind to PtdIns(3,4,5)P3 and a kinase domain of RimK superfamily. The proteins therefore show kinase activity which convert InsP6 and 5-InsP7 to 1-InsP7 and InsP8.
