Recombinant Human Glycine receptor subunit beta (GLRB), Truncated

Uniprot Id

P48167

Target Species

Human

Target Name

GLRB

Target Full Name

Glycine receptor subunit beta

Target Function

Glycine receptors are ligand-gated chloride channels. GLRB does not form ligand-gated ion channels by itself, but is part of heteromeric ligand-gated chloride channels. Channel opening is triggered by extracellular glycine. Heteropentameric channels composed of GLRB and GLRA1 are activated by lower glycine levels than homopentameric GLRA1. Plays an important role in the down-regulation of neuronal excitability. Contributes to the generation of inhibitory postsynaptic currents.

Target Involvement

Hyperekplexia 2 (HKPX2)

Target Subcellular Location

Cell junction, synapse, postsynaptic cell membrane; Multi-pass membrane protein. Cell junction, synapse. Cell projection, dendrite. Cell membrane; Multi-pass membrane protein. Cytoplasm.

Target Protein Families

Ligand-gated ion channel (TC 1.A.9) family, Glycine receptor (TC 1.A.9.3) subfamily, GLRB sub-subfamily

Target Synonyms

GLRBGlycine receptor subunit beta; Glycine receptor 58 kDa subunit

Target Background

This gene encodes the beta subunit of the glycine receptor, which is a pentamer composed of alpha and beta subunits. The receptor functions as a neurotransmitter-gated ion channel, which produces hyperpolarization via increased chloride conductance due to the binding of glycine to the receptor. Mutations in this gene cause startle disease, also known as hereditary hyperekplexia or congenital stiff-person syndrome, a disease characterized by muscular rigidity. Alternative splicing results in multiple transcript variants.
