LYK3 — Medicago truncatula

Summary

MTR_5G086080, also known as LYK3, encodes a CERK1/LYK3-like protein with a Ser-Thr/Tyr kinase catalytic domain, protein kinase domain, and kinase-like domain superfamily, and is annotated with chitin binding, transmembrane receptor protein kinase activity, signaling receptor activity, kinase activity, protein serine kinase activity, protein kinase activity, protein serine/threonine kinase activity, protein homodimerization activity, and ATP binding. In barrel medic, LYK3 is associated with nitrogen fixation, response to symbiotic bacteria, response to chitin, and innate immune response-activating signaling pathway. The gene is also linked to vesicle localization, endocytosis, regulation of reactive oxygen species metabolic process, hormone-mediated signaling, detection of brassinosteroid stimulus, flower morphogenesis, regulation of leaf senescence, sepal giant cell differentiation, plant epidermal cell differentiation, and chloroplast organization. LYK3 is localized to the plasma membrane, vacuolar lumen, and multivesicular body membrane. Related genes in other species link the family to chitin perception and immune signaling.
