ER1 — Pisum sativum

Summary

PSAT3G072480 (ER1, also known as PsPXC3) on garden pea chromosome 3LG5 encodes a transmembrane receptor protein tyrosine kinase belonging to the plant leucine-rich repeat receptor-like kinase (LRR-RLK) family. The encoded protein possesses serine/threonine and tyrosine kinase activity, ATP binding, steroid binding, SNARE binding, and protein heterodimerization activity. ER1 is associated with brassinosteroid stimulus detection, hormone-mediated signaling, stomatal complex morphogenesis and development, skotomorphogenesis, heat acclimation, salinity response, sporulation, embryo sac and ovule development, post-embryonic organ development, seedling development, and response to other organisms. The gene is linked to vascular development and localizes to the plasma membrane, endosome, and extracellular regions. Related genes in other species are associated with reduced stele size in seedlings.
