ER1 — Pisum sativum

Summary

PSAT7G213440 (ER1) on chromosome 7LG7 of garden pea (Pisum sativum) encodes a leucine-rich repeat (LRR) domain-containing protein with transmembrane receptor serine/threonine kinase activity, enzyme inhibitor activity, steroid binding, SNARE binding, and signaling receptor activity. The gene is associated with regulation of floral meristem size, floral organ development and specification of floral organ number, gametophyte development, sporulation, and microtubule bundling. It is linked to detection of brassinosteroid stimulus, hormone-mediated signaling, activation of defense response to bacteria, upregulation of defense response, response to other organisms, heat acclimation, skotomorphogenesis, seedling development, post-embryonic development, and regulation of cell growth. The encoded protein localizes to the ER membrane, cortical ER, perinuclear ER membrane, plasmalemma, endosome, nucleus, and extracellular region. Studies of related genes in other species link the family to additional developmental and defense-related processes.
