ER1 — Pisum sativum

Summary

PSAT3G053360 (ER1) on chromosome 3LG5 of garden pea encodes a transmembrane receptor protein serine/threonine kinase with leucine-rich repeat domains, exhibiting steroid binding, SNARE binding, and ATP binding activities. The gene is associated with detection of brassinosteroid stimulus, hormone-mediated signalling, protein phosphorylation, and regulation of stomatal complex development and morphogenesis. It is linked to sporulation, microtubule bundling, skotomorphogenesis, embryo sac and plant ovule development, seedling and post-embryonic development, heat acclimation, and activation of salinity response. Localisation evidence links the product to the ER membrane, plasmalemma, nucleus, endosome, and extracellular regions. Studies of related genes in other species connect the family to immune signalling and developmental regulation.
