Anti-ASH2 antibodies enable researchers to detect and measure the ASH2 antigen in biological samples. This target is a reported synonym of the ASCL2 gene, which encodes achaete-scute family bHLH transcription factor 2. This protein is known to function in the regulation of transcription and the regulation of cell differentiation, among other biological roles. The human version of ASH2 has a canonical amino acid length of 193 residues and a protein mass of 20.2 kilodaltons. It is reported to be localized in the nucleus of cells.
