Blm Gene Summary [Mouse]
Enables 3'-5' DNA helicase activity. Involved in DNA geometric change; negative regulation of mitotic recombination; and replication fork processing. Acts upstream of or within several processes, including DNA metabolic process; T cell differentiation; and positive regulation of T cell proliferation. Located in chromosome; cytoplasm; and nucleus. Is expressed in several structures, including brain; genitourinary system; gut; hemolymphoid system gland; and mammary gland. Used to study Bloom syndrome. Human ortholog(s) of this gene implicated in Bloom syndrome. Orthologous to human BLM (BLM RecQ like helicase). [provided by Alliance of Genome Resources, Jul 2025]

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