LYK3 — Medicago truncatula

Summary

MTR_3G080050, symbol LYK3, encodes a transmembrane receptor protein kinase with chitin-binding and protein tyrosine kinase activities, belonging to the LysM_RLK3/10 and CERK1/LYK3-like families. In barrel medic, LYK3 is associated with nitrogen fixation, response to symbiotic bacteria, detection of molecules of fungal origin, response to chitin, regulation of defence responses to fungi, upregulation of defense response to oomycetes, and regulation of reactive oxygen species metabolic processes. It has also been linked to endocytosis, vesicle localization, virus-induced PTGS, sepal giant cell differentiation, regulation of asymmetric cell division, flower morphogenesis, regulation of leaf senescence, and plant epidermal cell differentiation. The gene product localizes to the plasma membrane, multivesicular body membrane, and vacuolar lumen. Studies of related genes in other species link the LYK3 family to non-specific serine/threonine protein kinase activity.
