ER1 — Pisum sativum

Summary

PSAT7G018280 (symbol ER1) on garden pea chromosome 7LG7 encodes a protein with leucine-rich repeat and extensin-like domains, possessing protein serine/threonine kinase activity, ATP binding, steroid binding, SNARE binding, signaling receptor activity, and protein homo- and heterodimerization activities. The gene is associated with detection of brassinosteroid stimulus, hormone-mediated signaling, regulation of floral meristem size and floral organ development, specification of floral organ number, sporulation, megasporogenesis, microsporogenesis, anther wall tapetum development, gametophyte development, microtubule bundling, regulation of cell growth, skotomorphogenesis, heat acclimation, post-embryonic development, and response to other organisms. The encoded protein localizes to the ER membrane, perinuclear ER, cortical ER, plasmalemma, endosome, nucleus, and extracellular regions. Related genes in other species link the family to receptor kinase signaling.
