BRI1 — Brassica juncea

Summary

BJUB01G35940S (symbol BRI1, also known as BjECA4 or BjPICALM4A) on Indian mustard chromosome B01 encodes a protein with ANTH domain superfamily, ANTH_N_plant, AP180-like, ANTH_dom, ENTH, ENTH/VHS, Leu-rich_rpt, and LRR_dom_sf domains, and has transmembrane receptor protein kinase activity, protein serine/threonine kinase activity, steroid binding, clathrin heavy chain binding, and other molecular functions. The gene is associated with detection of brassinosteroid stimulus, hormone-mediated signalling, innate immune response activating cell surface receptor signaling pathway, vesicle formation, CME, regulation of meristem organisation, floral organ development, and other biological processes. It is linked to seed size, water use efficiency, drought tolerance, and ABA sensitivity. The product localises to the plasma membrane, clathrin-coated vesicles, endosomes, and vacuoles. Studies of related genes in other species connect the family to osmotic stress tolerance and protein trafficking.
