NOL1
Putative ribosomal RNA methyltransferase NOP2 is an enzyme that in humans is encoded by the NOP2 gene.[1][1][2]
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.[3]
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.[4]
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.[5]
Interactions
NOL1 has been shown to interact with MCRS1.[6]
