GNAL
Guanine
nucleotide-binding
protein
G
subunit
alpha
is a protein that in
humans
is
encoded
by the
GNAL
gene.
Its
main product
is the
heterotrimeric G-protein
alpha subunit
G
olf
-α, a member of the
Gs alpha subunit
family
that is a
key
component
of
G protein-coupled
receptor-regulated
adenylyl cyclase
signal transduction pathways
in the
olfactory system
and the
striatum
in
the brain
.
