ER1 — Pisum sativum

Summary

PSAT3G053320 (ER1) on chromosome 3LG5 of garden pea (Pisum sativum) encodes a transmembrane receptor protein serine/threonine kinase with ATP binding activity, belonging to a family containing leucine-rich repeats and a DNA repair-toleration domain. The gene is associated with the upregulation of defense and innate immune responses, activation of defense against bacteria, and regulation of defense against fungi. It is also linked to stomatal complex morphogenesis and development, regulation of cell growth, somatic embryogenesis, plant ovule and embryo sac development, heat acclimation, salinity response activation, and sporulation. The encoded protein localizes to the plasma membrane, endoplasmic reticulum membrane, early and late endosome membranes, and nucleus. Studies of related genes in other species link the family to immune responses.
