Glra1 Gene Summary [Rat]
Enables extracellularly glycine-gated chloride channel activity; glycine binding activity; and identical protein binding activity. Involved in chloride transport and glycinergic synaptic transmission. Located in endoplasmic reticulum and external side of plasma membrane. Is active in calyx of Held; glycinergic synapse; and synaptic membrane. Human ortholog(s) of this gene implicated in hyperekplexia 1. Orthologous to human GLRA1 (glycine receptor alpha 1).

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 Glra1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
