Nabp2 Gene Summary [Rat]
Predicted to enable DNA polymerase binding activity and G-rich strand telomeric DNA binding activity. Predicted to be involved in several processes, including establishment of protein localization to telomere; mitotic G2/M transition checkpoint; and positive regulation of telomere capping. Predicted to be located in chromosome; cytosol; and nucleoplasm. Predicted to be part of SOSS complex. Orthologous to human NABP2 (nucleic acid binding protein 2).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Nabp2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
