ER2 — Pisum sativum

Summary

PSAT4G140680 (symbol ER2) on chromosome 4LG4 of garden pea encodes a protein with malectin and leucine-rich repeat domains and serine/threonine kinase activity, annotated as a transmembrane receptor protein serine/threonine kinase. It is associated with steroid and SNARE binding, signaling receptor activity, and protein heterodimerization. The gene is linked to detection of brassinosteroid stimulus, hormone-mediated signalling, regulation of floral meristem size, specification of floral organ number, and anther wall tapetum development. It is also associated with megasporogenesis, microsporogenesis, embryo sac development, plant ovule development, stomatal complex morphogenesis, skotomorphogenesis, heat acclimation, and activation of salinity response. Localization evidence places the product at the membrane, plasmalemma, and endosome. Studies of related genes in other species link the family to non-specific serine/threonine protein kinase activity (EC 2.7.11.1).
