Anti-leucine-rich repeat LGI family member 2 antibodies enable researchers to detect and measure the leucine-rich repeat LGI family member 2 antigen in biological samples. This target is a reported synonym of the LGI2 gene, which encodes leucine rich repeat LGI family member 2. This protein is known to be required for the development of soma-targeting inhibitory GABAergic synapses made by parvalbumin-positive basket cells. The human version of leucine-rich repeat LGI family member 2 has a canonical amino acid length of 545 residues and a protein mass of 62.3 kilodaltons. It is reported to be a secreted protein that is notably expressed in many tissues, such as the caudate, testis, and bronchus.
