The protein encoded by this gene is a member of a G protein subfamily that mediates signal transduction in pertussis toxin-insensitive systms. This encoded protein may play a role in maintaining the ionic balance of perilymphatic and endolymphatic cochlear fluids. [provided by RefSeq, Jul 2008]
GeneCards Summary for GNAZ Gene
GNAZ (G Protein Subunit Alpha Z) is a Protein Coding gene. Diseases associated with GNAZ include Pertussis and Autosomal Dominant Congenital Stationary Night Blindness. Among its related pathways are Signaling by GPCR and Peptide ligand-binding receptors. GO annotations related to this gene include GTP binding and signal transducer activity. An important paralog of this gene is GNAI1.
UniProtKB/Swiss-Prot for GNAZ Gene
Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems.
Heterotrimeric G proteins are membrane bound GTPases that are linked to 7-TM receptors. Each G protein contains an alpha-, beta- and gamma-subunit and is bound to GDP in the 'off' state. Ligand binding causes a receptor conformational change, detaching the G protein and switching it 'on'.
