LPAT2 — Camelina sativa

Summary

CsLPAT4 (CSA16G038920) on Camelina sativa chromosome 16 encodes a lysophosphatidate acyltransferase with EC 2.3.1.51 activity, placing it in the glycerol-acyltransferase family. This gene is associated with CDP-diacylglycerol anabolism, fatty acid elongation, and glycerolipid biosynthesis, and has been linked to triacylglycerol accumulation, phospholipid biosynthesis, and nitrogen starvation response. CsLPAT4 is also associated with oleic acid content and seed size. The encoded protein localises to the endomembrane system, ER membrane, and mitochondria. Studies of related genes in other species link the family to thaumatin-like domains, though this is not established for CsLPAT4 itself.
