BRI1 — Solanum tuberosum

Summary

PGSC0003DMG400013198, also known as StIMK2, BRI1, or CURL3 on potato chromosome 9, encodes a leucine-rich repeat receptor-like kinase with a Ser/Thr kinase domain, exhibiting transmembrane receptor protein serine/threonine kinase activity, protein kinase activity, ATP binding, steroid binding, and coreceptor activity. This gene is associated with detection of brassinosteroid stimulus, hormone anabolism, regulation of cell growth, floral organ development and specification, pollen maturation, megasporogenesis, microsporogenesis, stomatal complex morphogenesis, skotomorphogenesis, immune complex formation, and virus-induced PTGS. It localizes to the plasma membrane, endosome, cytoplasm, pollen tube, and extracellular regions. Studies of related genes in other species link the family to protein kinase activity (EC 2.7.11.1) and tyrosine kinase activity (EC 2.7.10.1).
