ER1 — Pisum sativum

Summary

PSAT5G202120 (ER1) on garden pea chromosome 5LG3 encodes a protein with receptor serine/threonine kinase binding, protein serine kinase activity, and ATP binding, placing it in the protein kinase family. It contains domains including WD40 repeats, leucine-rich repeats, and TCP-1/chaperonin-like folds. The gene is associated with membrane and plasmalemma localization, and is linked to biological processes including defense response, heat acclimation, translation, regulation of cell growth, and sporulation. Studies of related genes in other species connect the family to non-canonical WD40-repeat functions and protein kinase signaling, though these associations are not yet established for pea.
