NPC4 — Camelina sativa

Summary

CsNPC4 (CSA01G003230) on Camelina sativa chromosome 1 encodes a phosphoesterase with alkaline phosphatase core domain, exhibiting phosphatidylcholine phospholipase C activity, inositol phosphorylceramide phospholipase activity, and calcium-dependent protein serine/threonine kinase activity. The gene is associated with phospholipid breakdown, glycolipid anabolism, unsaturated fatty acid anabolism, and triglyceride anabolism. It is linked to regulation of stomatal opening and closure, cellular responses to phosphate starvation, carbon dioxide, and absence of light, as well as abscisic acid-mediated signaling, osmotic response, defence response to bacteria, leaf development, and reactive oxygen species metabolism. Associations include seed yield, biomass yield, water use efficiency, leaf elongation rate, flowering time, root thickness, low temperature stress response, and salt tolerance. The protein localises to the cytosol, plasmalemma, cytoplasm, and nucleus. Studies of related genes in other species link the family to aluminum tolerance, stomatal ABA response, oil synthesis, and root growth.
