SUNN — Pisum sativum

Summary

PSAT3G142800 (symbol SUNN, also known as PsTMKL1) on garden pea chromosome 3LG5 encodes a kinase-like protein belonging to the plant leucine-rich repeat receptor-like kinase (LRR-RLK) family, with transmembrane receptor protein serine/threonine kinase activity, ATP binding, and steroid and SNARE binding capabilities. This gene is associated with nodulation, brassinosteroid and hormone-mediated signalling, detection of brassinosteroid stimulus, skotomorphogenesis, heat acclimation, defence response to fungi, and response to other organisms. It is linked to regulation of cell growth, cell differentiation, seedling and post-embryonic development, cytokinin anabolism, microtubule bundling, and protein phosphorylation. The encoded protein localises to the plasma membrane, endosome, plasmodesma, and extracellular regions. Studies of related LRR-RLK family members in other species link the family to non-specific serine/threonine kinase activity (EC 2.7.11.1).
