Guanine nucleotide-binding protein, beta subunit (IPR016346)

Short name: Guanine_nucleotide-bd_bsu

Overlapping homologous superfamilies

Family relationships



G protein is a modulator in various transmembrane signalling systems. The beta and gamma subunits are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction. This entry represents the G protein (guanine nucleotide-binding proteins) beta subunit, including Ste4 from budding yeasts [PMID: 2536595], Git5 from fission yeasts [PMID: 16884933] and GNB1-5 from animals [PMID: 26002831].
