Background Information

MKI67 gene encodes a nuclear protein, antigen KI-67, which was identified by monoclonal antibody Ki-67. Expression of this antigen occurs preferentially during late G1, S, G2 and M phases of the cell cycle, while in cells in G0 phase the antigen cannot be detected (PMID: 8227122). The antigen Ki-67 is a human nuclear protein the expression of which is strictly associated with cell proliferation and which is widely used in routine pathology as a "proliferation marker" to measure the growth fraction of cells in human tumors (PMID: 8227122).
