Guanine nucleotide-binding protein G(o) subunit alpha is a protein that in humans is encoded by the GNAO1 gene. This protein is part of the G_i/o family of G-proteins, which function by inhibiting adenylyl cyclase as part of G protein-coupled receptor signaling.

Mutations in this gene have been shown to cause epileptic encephalopathy.

Interactions

GNAO1 has been shown to interact with:

RGS5,
RGS19,
RGS20, and
RIC8A
