Siah2 Gene Summary [Mouse]
Enables ubiquitin protein ligase activity. Involved in regulation of circadian rhythm and ubiquitin-dependent protein catabolic process. Predicted to be located in several cellular components, including early endosome; neuronal cell body; and nucleoplasm. Predicted to be active in cytoplasm. Is expressed in several structures, including bone; brain; gonad; hemolymphoid system gland; and sensory organ. Orthologous to human SIAH2 (siah E3 ubiquitin protein ligase 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 mouse Siah2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
