LIPH(Lipase member H) is also named as LPDLR,MPAPLA1,PLA1B. It is a phosphatidic acid-selective phospholipase A1 (PLA1) that produces 2-acyl lysophosphatidic acid (LPA) and belongs to the AB hydrolase superfamily and Lipase family.LIPH has a 12-residue lid region,which likely covers a catalytic pocket,and 4 potential N-linked glycosylation sites. Defects in LIPH are the cause of hypotrichosis type 7 (HYPT7).
