Rabbit anti-Human GRID2 Polyclonal Antibody

Uniprot Id

O43424

Target Species

Human

Target Name

GRID2

Target Full Name

Glutamate receptor ionotropic, delta-2

Target Function

Receptor for glutamate. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. The postsynaptic actions of Glu are mediated by a variety of receptors that are named according to their selective agonists. Promotes synaptogenesis and mediates the D-Serine-dependent long term depression signals and AMPA receptor endocytosis of cerebellar parallel fiber-Purkinje cell (PF-PC) synapses through the beta-NRX1-CBLN1-GRID2 triad complex.

Target Involvement

Spinocerebellar ataxia, autosomal recessive, 18 (SCAR18)

Target Subcellular Location

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

Target Protein Families

Glutamate-gated ion channel (TC 1.A.10.1) family, GRID2 subfamily

Target Synonyms

delta-2; GluD2; GLUR D2; GluR delta 2; GluR delta-2 subunit; GLURD 2; GLURD2; Glutamate receptor delta 2 subunit ; Glutamate receptor ionotropic; Glutamate receptor ionotropic delta 2; GRID 2; Grid2; GRID2_HUMAN; MGC117022; MGC117023; MGC117024

Target Background

The protein encoded by this gene is a member of the family of ionotropic glutamate receptors which are the predominant excitatory neurotransmitter receptors in the mammalian brain. The encoded protein is a multi-pass membrane protein that is expressed selectively in cerebellar Purkinje cells. A point mutation in the mouse ortholog, associated with the phenotype named 'lurcher', in the heterozygous state leads to ataxia resulting from selective, cell-autonomous apoptosis of cerebellar Purkinje cells during postnatal development. Mice homozygous for this mutation die shortly after birth from massive loss of mid- and hindbrain neurons during late embryogenesis. This protein also plays a role in synapse organization between parallel fibers and Purkinje cells. Alternate splicing results in multiple transcript variants encoding distinct isoforms. Mutations in this gene cause cerebellar ataxia in humans.
