Antigen Ki-67 is a nuclear protein expressed in proliferating mammalian cells. It is widely used in cancer histopathology but its functions remain unclear. Here, we show that Ki-67 controls heterochromatin organisation. Altering Ki-67 expression levels did not significantly affect cell proliferation in vivo. Ki-67 mutant mice developed normally and cells lacking Ki-67 proliferated efficiently. Conversely, upregulation of Ki-67 expression in ... [more]

Additional Notes

• interactors identified using mass spectrometry, retaining hits for which either an untagged immunoprecipitation (IP) or IP of non-specific protein (TRIM39) produced fewer peptides hits and/or lower Mascot Scores
