Gabrb1 Gene Summary [Rat]

Enables GABA receptor binding activity; GABA-A receptor activity; and monoatomic ion channel activity. Involved in several processes, including cellular response to histamine; central nervous system neuron development; and response to progesterone. Located in dendrite; nuclear envelope; and plasma membrane. Part of GABA-A receptor complex. Is active in GABA-ergic synapse; postsynaptic specialization membrane; and presynaptic active zone membrane. Biomarker of hepatic encephalopathy. Human ortholog(s) of this gene implicated in autistic disorder and developmental and epileptic encephalopathy 45. Orthologous to human GABRB1 (gamma-aminobutyric acid type A receptor subunit beta1).

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Gabrb1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
