WebNov 21, 2024 · DNMT1-specific immune reactive bands corresponding to a predicted 200 kDa were observed in the protein preparations from hRPTCs expressing GPR37L1-GFP, but not with the control IgG. DNMT1-specific immunoreactive bands were absent in the Co-IP of protein preparation from mock-transfected cells using control IgG or GFP antibody . WebDNMT1 is crucial for mammalian development, proliferation and survival of cancer cells (6-9). It attaches a methyl group to the carbon-5 (C5) position of cytosine residues using AdoMet as a cofactor. With an unmethylated DNA substrate, the full-length DNMT1 is catalytically poor compared to its activity on the same hemimethylated DNA sequence (10).
