Organism
Arabidopsis thaliana
Function
Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems (By similarity). Binds GTP with specificity. Plays a role in the root morphogenesis by regulation of the cell proliferation. Acts with GB1 in the positive regulation of root waving and root skewing.
Similarity
Belongs to the G-alpha family. XLG subfamily.
