Anti-EHB3 antibodies enable researchers to detect and measure the EHB3 antigen in biological samples. This target is a reported synonym of the CDC40 gene, which encodes cell division cycle 40. This protein is known to function in RNA splicing, among other biological roles. The human version of EHB3 has a canonical amino acid length of 579 residues and a protein mass of 65.5 kilodaltons. It is reported to be localized in the nucleus of cells. Other names for this target antigen include PCH15 and PRP17.
