Lysophospholipase-like 1 is a protein in humans that is encoded by the LYPLAL1 gene. [1] The protein is a α/β-hydrolase of uncharacterized metabolic function. Genome-wide association studies in humans have linked the gene to fat distribution[2] and waist-to-hip ratio.[3] The protein's enzymatic function is unclear. LYPLAL1 was reported to act as a triglyceride lipase in adipose tissue[4] and another study suggested that the protein may play a role in the depalmitoylation of calcium-activated potassium channels.[5] However, LYPLAL1 does not depalmitoylate the oncogene Ras[6] and a structural and enzymatic study concluded that LYPLAL1 is generally unable to act as a lipase and is instead an esterase that prefers short-chain substrates, such as acetyl groups.[7]

Model organisms

Model organisms have been used in the study of LYPLAL1 function. A conditional knockout mouse line called Lyplal1tm1a(KOMP)Wtsi was generated at the Wellcome Trust Sanger Institute.[8] Male and female animals underwent a standardized phenotypic screen[9] to determine the effects of deletion.[10][11][12][13] Additional screens performed: - In-depth immunological phenotyping[14]
