Anti-Sac3 antibodies are used in antigen-specific immunodetection in biological samples. The target Sac3 is a known alias name of the protein minichromosome maintenance complex component 3 associated protein, encoded by the MCM3AP gene in humans. This 1980-amino acid residue protein is known to be involved in protein transport, among other biological processes. It is localized to the nucleus of the cell. In terms of tissue expression, it is widely expressed across many tissue types.
