Ready-to-use ELISA kits are available for the detection of p127-DDB1, an alias of the protein, damage specific DNA binding protein 1. The official gene symbol is DDB1. The kits can detect several species variants of the protein, including: bovine and chicken. The protein, with a mass of 127 kDa and length of 1140 residues, is reported to be cytoplasmic and nuclear. It is a member of the DDB1 family and may be known by other names, including: UV-damaged DNA-binding protein 1, UV-damaged DNA-binding factor, HBV X-associated protein 1, DNA damage-binding protein a, DDB p127 subunit, and DNA damage-binding protein 1, and XPE-binding factor.
