Tdp1 Gene Summary [Mouse]

Predicted to enable 3'-tyrosyl-DNA phosphodiesterase activity; double-stranded DNA binding activity; and single-stranded DNA binding activity. Acts upstream of or within single strand break repair. Located in nucleus. Is expressed in ovary and testis. Used to study spinocerebellar ataxia with axonal neuropathy 1. Human ortholog(s) of this gene implicated in spinocerebellar ataxia with axonal neuropathy 1. Orthologous to human TDP1 (tyrosyl-DNA phosphodiesterase 1).

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 mouse Tdp1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
