ER1 — Pisum sativum

Summary

PSAT5G234240 (symbol ER1) on chromosome 5LG3 of garden pea encodes a protein with malectin and leucine-rich repeat domains, possessing protein serine/threonine kinase activity, signaling receptor activity, and steroid, SNARE, and ATP binding. It is associated with brassinosteroid stimulus detection, hormone-mediated signaling, and the upregulation of defense responses, including activation of defense against bacteria. The gene is linked to sporulation, megasporogenesis, microsporogenesis, anther wall tapetum development, skotomorphogenesis, heat acclimation, seedling development, and post-embryonic development. It localizes to the plasma membrane, ER membrane, endosome, and nucleus. Studies of related genes in other species connect the family to immune signaling and receptor kinase functions.
