Preparation and Storage

Background: Lipase I

Lipase I (Lipase member I; also mPA‑PLA₁ beta  LPDL and PLA1C) is a 55 kDa member of the PLA₁ subfamily, pancreatic lipase family, AB hydrolase superfamily of enzymes. It is expressed by sperm, where it is apparently secreted and subsequently binds to membrane-associated HSPGs. Lipase I hydrolyzes phosphatidic acid to generate 2‑acyl‑LPA, which then activates one of four G-protein coupled receptors. Human Lipase I precursor is 460 amino acids (aa) in length. It contains a 15 aa signal sequence, followed by an active catalytic site composed of Ser159, Asp183 and His268. Lipase I is known to be phosphorylated on Ser25. There are two isoform variants, both of which show a 34 aa substitution for aa 1‑13, and only one of which shows an eight aa substitution for aa 245‑460. Over aa 14‑154, human Lipase I shares 61% aa identity with mouse Lipase I.
