NOL1 Proteins and Enzymes

Nucleolar protein 1 (NOL1) is a protein highly expressed in proliferating cells; it is expressed in G1 and peaks during early S phase. It is proposed to play a role in the regulation of the cell cycle, and it may function as a ribosomal RNA methyltransferase. Alternative names for NOL1 include p120 nucleolar-proliferation antigen, nucleolar protein 2 homolog, proliferating-cell nucleolar antigen p120, proliferation-associated nucleolar protein p120, NSUN1, and NOP2.
