Anti-WDR28 antibodies enable researchers to detect and measure the WDR28 antigen in biological samples. This target is a reported synonym of the GRWD1 gene, which encodes glutamate rich WD repeat containing 1. This protein is known to function in DNA replication, among other biological roles. The human version of WDR28 has a canonical amino acid length of 446 residues and a protein mass of 49.4 kilodaltons. It is reported to be localized in the nucleus of cells and notably expressed in many tissues, such as the bronchus, urinary bladder, and adrenal gland.
