NPC4 — Camelina sativa

Summary

CsNPC4 (CSA15G003300) on Camelina sativa chromosome 15 encodes a phosphoesterase with an alkaline phosphatase core domain, exhibiting phosphatidylcholine phospholipase C activity (EC 3.1.4.3), inositol phosphorylceramide phospholipase activity, and calcium-dependent protein serine/threonine kinase activity. The gene is associated with phospholipid breakdown, glycolipid anabolism, unsaturated fatty acid and triglyceride anabolism, and regulation of stomatal opening, closure, and movement. It is linked to cellular responses to phosphate starvation, carbon dioxide, and absence of light, as well as abscisic acid-mediated signaling, reactive oxygen species metabolism, seed and leaf development, and osmotic response. Associations include biomass yield, seed yield, water use efficiency, leaf elongation rate, root thickness, flowering time, and stress responses to low temperature and salt. The protein localizes to the cytosol, plasma membrane, cytoplasm, and nucleus. Related genes in other species connect it to aluminum tolerance, root growth, ABA signaling in stomata, oil synthesis, and cuticle formation.
