ER1 — Pisum sativum

Summary

PSAT0S4118G0120, designated ER1 in garden pea (Pisum sativum) on chromosome CAADHX020011644.1, encodes a transmembrane receptor protein serine/threonine kinase with protein kinase activity and ATP binding. The product contains leucine-rich repeat domains and belongs to the RLP_Defense family. ER1 is associated with diverse biological processes including sporulation, floral organ development, regulation of meristem organisation and floral meristem size, gametophyte development, megasporogenesis, microsporogenesis, anther wall tapetum development, stomatal complex morphogenesis, and regulation of cell growth. It is linked to activation of defence responses to bacteria, upregulation of defence response, and activation of salinity response. The protein localises to the endoplasmic reticulum membrane, perinuclear ER membrane, cortical ER, plasmalemma, nucleus, and extracellular region. Studies of related genes in other species connect the family to receptor kinase signalling.
