The PLA2G1B protein is a secreted calcium-dependent phospholipase A2 that targets dietary phospholipids in the intestine. It hydrolyzes the fatty acyl group at the sn-2 position, preferentially hydrolyzing phosphatidylethanolamine and phosphatidylglycerol. PLA2G1B Protein, Human (HEK293, His) is the recombinant human-derived PLA2G1B protein, expressed by HEK293 , with C-6*His labeled tag.
