Micu2 Gene Summary [Rat]
Predicted to enable several functions, including calcium channel regulator activity; calcium ion sensor activity; and protein heterodimerization activity. Predicted to be involved in calcium import into the mitochondrion; cellular response to calcium ion; and mitochondrial calcium ion homeostasis. Predicted to be located in mitochondrial inner membrane and mitochondrial intermembrane space. Predicted to be part of uniplex complex. Orthologous to human MICU2 (mitochondrial calcium uptake 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 rat Micu2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
