Putative phospholipase. Interacts with IGF2R. Present at highest levels in spleen, lung and brain (at protein level). The p76 protein is synthesized as a 76 kDa precursor which is then processed into a N-terminal 28 kDa form and a C-terminal 40 kDa form. The C-terminal peptide is further processed into a 15 kDa form. Glycosylated; contains mannose 6-phosphate sugars. Belongs to the phospholipase B-like family.
