Ddb1 Gene Summary [Mouse]
Predicted to enable several functions, including WD40-repeat domain binding activity; cullin family protein binding activity; and ubiquitin ligase complex scaffold activity. Involved in several processes, including cellular response to UV; positive regulation of gluconeogenesis; and ubiquitin-dependent protein catabolic process. Acts upstream of or within several processes, including Wnt signaling pathway; negative regulation of apoptotic process; and negative regulation of reproductive process. Part of Cul4A-RING E3 ubiquitin ligase complex. Is expressed in several structures, including blastocyst; early embryo; germ cell of gonad; otocyst; and spleen. Human ortholog(s) of this gene implicated in communication disorder. Orthologous to human DDB1 (damage specific DNA binding protein 1). [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 Ddb1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
