The antigen is a fusion protein from the N-terminal region of the δ-subunit of rat GABAA receptor.

The antibody is prepared from pooled 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 as, four bs and four gs, 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 a- and b-subunits results in the expression of functional GABAA-Rs sensitive to GABA. However, co-expression of a g-subunit is required for benzodiazepine modulation.  The various effects of the benzodiazepines in brain may also be mediated via different a-subunits of the receptor (McKernan et al., 2000; Mehta and Ticku, 1998; Ogris et al., 2004; Pöltl et al., 2003).  More recently there have been a number of studies demonstrating that the δ-subunit of the receptor may affect subunit assembly (Korpi et al., 2002) and may also confer differential sensitivity to neurosteroids and to ethanol (Wallner et al., 2003; Wohlfarth et al., 2002).
