Guanine nucleotide-binding protein alpha-1 subunit

UniProtKB accession:  A2Y3B5

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. May function in a signal transduction pathway required for normal growth and development of internodes, leaves, panicles and seeds. Involved in gibberellin signal transduction. Involved in R gene-mediated disease resistance. Functions upstream of the small GTPase RAC1 in the early steps of signaling. Involved in brassinosteroid response. May not be a signaling molecule in BRI1-mediated perception or transduction.
