The antigen is a fusion protein from the cytoplasmic loop of the ?2-subunit of rat GABAA receptor.

The antibody is prepared from rabbit serum by affinity purification using a column to which the fusion protein immunogen was coupled.

Biological Significance: ExpandCollapse

Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the central nervous system, causing a hyperpolarization of the membrane through the opening of a Cl? channel associated with the GABAA receptor (GABAA-R) subtype. GABAA-Rs are important therapeutic targets for a range of sedative, anxiolytic, and hypnotic agents and are implicated in several diseases including epilepsy, anxiety, depression, and substance abuse. The GABAA-R is a multimeric subunit complex. To date six ?s, four ?s and four ?s, plus alternative splicing variants of some of these subunits, have been identified (Olsen and Tobin, 1990; Whiting et al., 1999; Ogris et al., 2004). Injection in oocytes or mammalian cell lines of cRNA coding for ?- and ?-subunits results in the expression of functional GABAA-Rs sensitive to GABA. However, coexpression of a ?-subunit is required for benzodiazepine modulation. The various effects of the benzodiazepines in brain may also be mediated via different ?- subunits of the receptor (McKernan et al., 2000; Mehta and Ticku, 1998; Ogris et al., 2004; Pöltl et al., 2003).

GABA A Receptor alpha 2 Antibody
Western blot of mouse brain lysates from wild type (WT) and ?2-knockout (K/O) animals showing specific immunolabeling of the ~51 kDa ?2-subunit of the GABAA-R. The labeling was absent from a lysate prepared from ?2-knockout animals.
