Summary
Enables GTP binding activity and GTPase activity. Acts upstream of or within several processes, including G protein-coupled receptor signaling pathway; dopamine receptor signaling pathway; and locomotory behavior. Located in cell body and dendrite. Is expressed in several structures, including alimentary system; brain; ganglia; genitourinary system; and sensory organ. Used to study developmental and epileptic encephalopathy 17 and neurodevelopmental disorder with involuntary movements. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 17 and neurodevelopmental disorder with involuntary movements. Orthologous to human GNAO1 (G protein subunit alpha o1). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
