STMPK3 — Solanum tuberosum

Summary

PGSC0003DMG400012188, symbol STMPK3, on potato chromosome 8, encodes a mitogen-activated protein kinase (MAPK) with serine/threonine kinase activity and MAPKK activity, classified as EC 2.7.11.24. The gene is associated with the MAPK cascade, intracellular signal transduction, and the PRR signaling pathway. It is linked to diverse biological processes including zeatin and carotenoid anabolism, phytoalexin and isoflavonoid biosynthesis, secondary metabolite and fatty acid anabolism, sucrose metabolism, glutathione metabolism, phloem loading, stomatal closure, response to UV-C, and chlorophyll fluorescence. The encoded protein localizes to the cytoplasm and nucleus. STMPK3 is also associated with starch content and salt tolerance (SALTTL). Related genes in other species link the family to salicylic acid signaling.
