Function

The protein encoded by this gene binds to an anti-proliferative protein, B-cell translocation protein 1, which negatively regulates cell proliferation. Binding of the two proteins, which is driven by phosphorylation of the anti-proliferative protein, causes signaling events in cell division that lead to changes in cell proliferation associated with cell-cell contact. The protein has both mouse and yeast orthologs. Alternate splicing of this gene results in two transcript variants encoding different isoforms.[8]

Interactions

CNOT7 has been shown to interact with:

• BTG1,[9][10]
• PABPC1,[11]
• TOB1,[11][12] and
• TOB2.[12]
