Guanine nucleotide-binding protein G(z) subunit alpha is a protein that in humans is encoded by the GNAZ gene.[5][6]

Function[edit]

The protein encoded by this gene is a member of a G protein subfamily that mediates signal transduction in pertussis toxin-insensitive systems. This encoded protein may play a role in maintaining the ionic balance of perilymphatic and endolymphatic cochlear fluids.[6]

Interactions[edit]

GNAZ has been shown to interact with EYA2,[7] RGS20[8][9] and RGS19.[7][10]
