GNG5 (G Protein Subunit Gamma 5) is a widely expressed gamma subunit of heterotrimeric G proteins. GNG5 combines with various Gβ subunits to form functionally diverse Gβγ complexes that regulate numerous cellular effectors. In the nervous system, GNG5 participates in signaling pathways controlling neuronal excitability, neurotransmitter release, and gene expression. GNG5 is essential for normal development and cellular function, with knockout leading to embryonic lethality in mice.
GNG5 encodes the G protein gamma 5 subunit, a widely expressed gamma subunit that partners with various beta subunits. It is involved in diverse signaling pathways including modulation of ion channels and second messenger systems.
Ubiquitously expressed with high levels in brain and endocrine tissues. Involved in general G protein signaling.
| Disease | Variants | Inheritance | Mechanism |
