Anti-P1-CDC46 antibodies enable researchers to detect and measure the P1-CDC46 antigen in biological samples. This target is a reported synonym of the MCM5 gene, which encodes minichromosome maintenance complex component 5. This protein is known to function in the cell cycle and DNA replication, among other biological roles. The human version of P1-CDC46 has a canonical amino acid length of 734 residues and a protein mass of 82.3 kilodaltons. It is reported to be localized in the nucleus and chromosomes of cells and widely expressed in many tissue types. Other names for this target antigen include CDC46, MGORS8, and P1-CDC46.
