Anti-GS188 antibodies enable researchers to detect and measure the GS188 antigen in biological samples. This target is a reported synonym of the TMEM176A gene, which encodes transmembrane protein 176A. This protein is known to function in the regulation of cell differentiation, among other biological roles. The human version of GS188 has a canonical amino acid length of 235 residues and a protein mass of 26.1 kilodaltons. It is reported to be localized in the membrane of cells and widely expressed in many tissue types. GS188 is a member of the TMEM176 protein family.
