The protein encoded by this gene is a nucleolar antigen expressed in proliferating cells. It is not detectable in non-proliferating normal tissue but is detectable in many human tumors.[7]

Overexpression of p120 leads to malignant transformation of 3T3 cells while treatment with antisense p120 mRNA causes the transformed cells to revert to their original non-malignant phenotype.[8] The p120 protein displays a dramatic increase in expression at the G1/S transition suggesting that p120 regulates the cell cycle and nucleolar activity that is required for cell proliferation.[9]

Interactions

NOL1 has been shown to interact with MCRS1.[10]
