Samhd1 Gene Summary [Mouse]
Enables dGTPase activity. Involved in several processes, including negative regulation of type I interferon-mediated signaling pathway; protein homotetramerization; and somatic hypermutation of immunoglobulin genes. Predicted to be located in nucleoplasm; site of double-strand break; and tetraspanin-enriched microdomain. Predicted to be active in nucleus. Is expressed in left lung; right lung; and thymus primordium. Human ortholog(s) of this gene implicated in Aicardi-Goutieres syndrome; Chilblain lupus; acute myeloid leukemia; hepatitis B; and hepatitis C. Orthologous to human SAMHD1 (SAM and HD domain containing deoxynucleoside triphosphate triphosphohydrolase 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 Samhd1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
