Lipid remodeling steps consist in the generation of 2 saturated fatty chains at the sn-2 position of GPI-anchor proteins (GPI-AP). Has phospholipase A2 activity that removes an acyl-chain at the sn-2 position of GPI-anchors during the remodeling of GPI. Required for the shedding of the GPI-AP TDGF1, but not CFC1, at the cell surface. Shedding of TDGF1 modulates Nodal signaling by allowing soluble TDGF1 to act as a Nodal coreceptor on other cells (PubMed:27881714). Also indirectly involved in the translocation of RAC1 from the cytosol to the plasma membrane by maintaining the steady state amount of CAV1-enriched plasma membrane subdomains, stabilizing RAC1 at the plasma membrane (PubMed:27835684). In contrast to myomaker (TMEM8C), has no fusogenic activity (PubMed:26858401). {ECO:0000269|PubMed:26858401, ECO:0000269|PubMed:27835684, ECO:0000269|PubMed:27881714}. |DUF3522| |phospholipase A2 activity (consuming 1,2-dipalmitoylphosphatidylcholine)| |phospholipase A2 activity consuming 1,2-dioleoylphosphatidylethanolamine)| |phospholipase A2 activity| |lysosomal membrane| |molecular function| |integral component of plasma membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp8|Brefeldin A 0.02μM R00 exp8]]|-2.11| |[[:results:exp484|GSK-J5 1.5μM R08 exp484]]|-1.83| |[[:results:exp492|iCRT14 30μM R08 exp492]]|-1.79| |[[:results:exp34|Rotenone 20μM R00 exp34]]|-1.77| No correlation found to any other genes in chemogenomics.
