PGIP — Beta vulgaris subsp. vulgaris

Summary

BVRB_3G060700 (symbol PGIP) on sugar beet chromosome 3 encodes a polygalacturonase-inhibiting protein (PGIP) with leucine-rich repeat domains and exhibits enzyme inhibitor activity, transmembrane receptor protein kinase activity, receptor serine/threonine kinase binding, protein serine kinase activity, and ATP binding. The gene is associated with defense response, response to other organisms, heat acclimation, protein phosphorylation, signal transduction, regulation of floral meristem size, specification of floral organ number, floral organ development, gametophyte development, regulation of cell growth, post-embryonic development, and cell differentiation. Its product localizes to the apoplast, extracellular region, membrane, and plasmalemma. Studies of related genes in other species link the family to serine/threonine protein kinase activity (EC 2.7.11.1).
