85 kDa calcium-independent phospholipase A2 is an enzyme that in humans is encoded by the PLA2G6 gene.[1][2][3][4]

Function

The protein encoded by this gene is a phospholipase A2 enzyme, a subclass of enzyme that catalyzes the release of fatty acids from phospholipids. The encoded protein may play a role in phospholipid remodelling, arachidonic acid release, leukotriene and prostaglandin synthesis, Fas receptor-mediated apoptosis, and transmembrane ion flux in glucose-stimulated B-cells. Several transcript variants encoding multiple isoforms have been described, but the full-length nature of only two of them have been determined to date.[4]

Model organisms

Model organisms have been used in the study of PLA2G6 function. A conditional knockout mouse line called Pla2g6tm1a(EUCOMM)Wtsi was generated at the Wellcome Trust Sanger Institute.[5] Male and female animals underwent a standardized phenotypic screen[6] to determine the effects of deletion.[7][8][9][10] Additional screens performed: - In-depth immunological phenotyping[11]
