S-SHIP is an alias for the gene, Inositol polyphosphate-5-phosphatase D, in humans. Other names include: Phosphatidylinositol 3,4,5-trisphosphate 5-phosphatase 1; Inositol polyphosphate-5-phosphatase of 145 kDa; SIP-145; SH2 domain-containing inositol 5'-phosphatase 1; SH2 domain-containing inositol phosphatase 1; SHIP-1; p150Ship; hp51CN; Phosphatidylinositol 3,4,5-trisphosphate 5-phosphatase 1 ; SHIP; SHIP1; inositol polyphosphate-5-phosphatase, 145kDa. The encoded protein is an enzyme with an amino acid length of 1189 and a mass of 133.3 kDa. Other isoforms may exist. S-SHIP is a member of the Inositol 1,4,5-trisphosphate 5-phosphatase family. This gene shares homology with other species, including: Mouse.
