Protein-coding gene in the species Homo sapiens
Guanine nucleotide-binding protein G(z) subunit alpha is a protein that in humans is encoded by the GNAZ gene .[ 5] [ 6]
Function
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
GNAZ has been shown to interact with EYA2 ,[ 7] RGS20 [ 8] [ 9] RGS19 .[ 7] [ 10]
