UniProtKB - O80462 (XLG1_ARATH)
Protein
Extra-large guanine nucleotide-binding protein 1
Gene
XLG1
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
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.By similarity1 Publication
Miscellaneous
Dark-grown xlg1-1 xlg2-1 xlg3-1 triple mutant plants showed markedly increased primary root length compared with wild-type plants. Dark-grown roots of the xlg triple mutants also showed altered sensitivity to sugars, abscisic acid (ABA) hyposensitivity and ethylene hypersensitivity, whereas seed germination in xlg triple mutants was hypersensitive to osmotic stress and ABA (PubMed:17999646).1 Publication
