Gene Information

human ... MKI67(4288)

General description

Ki-67 is a nuclear protein, which is expressed in the proliferating cells. Ki-67 is preferentially expressed during late G1-, S-, M-, and G2-phases of the cell cycle, while cells in the G0 (quiescent) phase are negative for this protein.
The gene marker of proliferation Ki-67 (MKI67), spanning 15 exons, is mapped to human chromosome 10q26.2. The encoded protein contains phosphopeptide-binding forkhead-associated (FHA) domain and a protein phosphatase 1 (PP1)-binding site at N- terminal. It possesses 16 tandem repeats at central region and leucine and arginine (LR) pairs at C- terminal end.


Synthetic peptide from C-terminus of human Ki-67 protein.


Anti-KI-67 antibody, Rabbit monoclonal has been used in immunohistochemistry.

Biochem/physiol Actions

Marker of proliferation Ki-67 (MKI67), which is a part of the mitotic chromosome periphery, functions as a biological surfactant to maintain individual mitotic chromosomes dispersed in the cytoplasm after nuclear envelope disassembly. Ki-67 is a vital prognostic marker in breast and prostate cancer. Expression of the encoded protein is associated with cell-proliferation rate. Ki-67 is expressed at all active phases of the cell cycle (G (1), S, G (2), and mitosis), except resting cells (G (0)). Therefore, this protein is considered to be a potent cell proliferation marker.
