Anti-ODD antibodies enable researchers to detect and measure the ODD antigen in biological samples. This target is a reported synonym of the OSR1 gene, which encodes odd-skipped related transcription factor 1. This protein is known to function in the differentiation of certain cell types, among other biological roles. The human version of ODD has a canonical amino acid length of 266 residues and a protein mass of 29.6 kilodaltons. It is reported to be localized in the nucleus of cells. ODD is a member of the Odd C2H2-type zinc-finger protein family.
