Anti-cholinergic receptor, nicotinic, alpha 2 (neuronal) antibodies enable researchers to detect and measure the cholinergic receptor, nicotinic, alpha 2 (neuronal) antigen in biological samples. This target is a reported synonym of the CHRNA2 gene, which encodes cholinergic receptor nicotinic alpha 2 subunit. This protein is known to function in chemical synaptic transmission and the transport of ions, among other biological roles. The human version of cholinergic receptor, nicotinic, alpha 2 (neuronal) has a canonical amino acid length of 529 residues and a protein mass of 59.8 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include neuronal acetylcholine receptor subunit alpha-2, acetylcholine receptor, nicotinic, alpha 2 (neuronal), and cholinergic receptor, nicotinic alpha 2.
