UniprotKB/SwissProt ID: Q0DJ33 (Q0DJ33)
Gene Name:
GPA1
Organism: Oryza sativa subsp. japonica (Rice)
Function: Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems (Probable). May function in a signal transduction pathway required for normal growth and development of internodes, leaves, panicles and seeds (PubMed:10377457). Involved in gibberellin signal transduction (PubMed:10468600, PubMed:11027362). Involved in R gene-mediated disease resistance. Functions upstream of the small GTPase RAC1 in the early steps of signaling (PubMed:12237405). Involved in brassinosteroid (BR) response. May not be a signaling molecule in BRI1-mediated perception or transduction (PubMed:17117160, PubMed:19036785). Acts together with the E3 ubiquitin ligase TUD1 to mediate a BR signaling pathway that affects plant growth and development (PubMed:23526892)
