ER1 — Pisum sativum

Summary

PSAT5G146960 (symbol ER1, also known as PsHAK1) on garden pea chromosome 5LG3 encodes a protein with transmembrane receptor protein serine/threonine kinase activity, protein kinase activity, and ATP binding, containing leucine-rich repeat and protein kinase domains. The gene is associated with detection of molecules of fungal origin, innate immune response-activating signaling, response to fungal molecules, and upregulation of reactive oxygen species anabolism. It has been connected to brassinosteroid sensitivity and signaling, defense and herbivore defense responses, root elongation, shade avoidance, reduced hypocotyl length, and reduced brassinolide response. Localization evidence links the product to the plasma membrane, nucleus, endosome, and plasmodesmata. Related genes in other species are associated with brassinosteroid signaling, root elongation, and herbivore resistance.
