NIFK: Proteins and Enzymes

NIFK is a nucleolar protein that interacts with Ki67, a protein strongly associated with, and a specific marker of, cell proliferation. The marsupial counterpart of human NIFK was recently identified and suggests that NIFK may be involved in the organization of higher order chromatin structure. NIFK was found to interact with the forkhead associated domain of Ki67 in mitotic cells and the interaction is thought to be phosphorylation-dependent.
