Pot1b

Enables single-stranded telomeric DNA binding activity and small GTPase binding activity. Acts upstream of or within several processes, including cellular senescence; negative regulation of DNA recombination at telomere; and protection from non-homologous end joining at telomere. Located in chromosome, telomeric region. Part of nuclear telomere cap complex. Is expressed in several structures, including brain; genitourinary system; liver; musculature; and spleen. Human ortholog(s) of this gene implicated in colorectal cancer; familial melanoma; hepatocellular carcinoma; lung cancer; and ovarian cancer. Orthologous to human POT1 (protection of telomeres 1).

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 mouse Pot1b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.

The most significant associations for this gene, including commonly observed domains, pathway involvement, and functional highlights based on current data.

Locations within the cell where the protein is known or predicted to be active, providing insight into its function and cellular context.
