Micu1 Gene Summary [Mouse]
Enables calcium ion binding activity; calcium ion sensor activity; and protein heterodimerization activity. Involved in calcium import into the mitochondrion and positive regulation of cristae formation. Located in mitochondrial intermembrane space. Part of calcium channel complex. Is active in mitochondrial inner membrane. Is expressed in several structures, including genitourinary system; liver; nervous system; parathyroid gland; and respiratory system. Human ortholog(s) of this gene implicated in myopathy with extrapyramidal signs. Orthologous to human MICU1 (mitochondrial calcium uptake 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 Micu1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
