Protein function
Encodes a guanine nucleotide-binding proteins subunit involved in multiple signal transduction pathways.
Phenotype
Single mutant: rack1a single mutant is late flowering under both SD and LD conditions, but only in terms of days to flowering. (
rack1a single mutant has a longer plastochron.)
[Chen et al., 2006] Remarks: RACK1A is involved in multiple developmental processes.
[Chen et al., 2006][Guo et al., 2011][Kundu et al., 2013] Function:Major component of the RACK1 regulatory proteins that play a role in multiple signal transduction pathways. Involved in multiple hormone responses and developmental processes (PubMed:16829549, PubMed:18715992, PubMed:18947417). MAPK cascade scaffolding protein involved in the protease IV and ArgC signaling pathway but not the flg22 pathway (PubMed:25731164).
