Specific for ~45k GABAA receptor gamma y2 subunit phosphorylated at Ser327 in Western Blots of rat brain homogenate.

Affinity Purified (Prepared from rabbit serum by affinity purification via sequential chromatography on phospho- and dephospho-peptide affinity columns.)

100 ul in 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 ug per ml BSA and 50% glycerol. Adequate amount of material to conduct 10-mini Western Blots.

For long term storage ~80 degree C is recommended, but shorter term storage at ~20 degree C is also acceptable as aliquots maybe taken without freeze/thawing due to the presence of 50% glycerol. Stock solutions are stable for a minimum of 1 year at -20 degree C.

Dot Blots (DB), Western Blot (WB)

Quality Control: . DB: 1:1000. WB: 1:1000. Quality Control Tests: Western Blots performed on each lot.

Antigen: Phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser327 of the GABAA receptor, gamma2 subunit. Immunogen Information: Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser327 conjugated to KLH. Immunogen Species: Rat

Species Reactivity Note: The antibody has been directly tested for reactivity in Western blots with rat tissue. It is anticipated that the antibody will react with bovine, canine, chicken, mouse, human and non-human primate tissues based on the fact that these species have 100% homology with the amino acid sequence used as antigen. Biological Significance: Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the central nervous system. There are two major classes of GABA receptors: the GABAA and the GABAB subtype of receptors. 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 sub-stance abuse. The GABAA-R is a multimeric subunit complex. To date six alphas, four betas and four gammas, 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 alpha- and beta-subunits results in the expression of functional GABAA-Rs sensitive to GABA. However, coexpression of a gamma-subunit is required for benzodiazepine modulation. It has recently been suggested that PKCepsilon regulates the sensitivity of GABAA alpha1beta2gamma2 receptors to ethanol and benzodiazepines through phosphorylation of serine 327 in the large intracellular loop of gamma2 (Qi et al., 2007)

subunit of GABA receptors, which bind benzodiazepines and act as inhibitory ion channels in the brain [RGD, Feb 2006]

Function: GABA, the major inhibitory neurotransmitter in the vertebrate brain, mediates neuronal inhibition by binding to the GABA/benzodiazepine receptor and opening an integral chloride channel. Subunit structure: Generally pentameric. There are five types of GABA(A) receptor chains: alpha, beta, gamma, delta, and rho. Subcellular location: Cell junction synapse postsynaptic cell membrane; Multi-pass membrane protein. Cell membrane; Multi-pass membrane protein. Post-translational modification: Palmitoylated by ZDHHC3/GODZ; which may affect presynaptic clustering and/or cell surface stability . By similarity. Miscellaneous: This subunit carries the benzodiazepine binding site. Sequence similarities: Belongs to the ligand-gated ion channel (TC 1.A.9) family. Gamma-aminobutyric acid receptor (TC 1.A.9.5) subfamily. GABRG2 sub-subfamily. [View classification]
