Abcb7 Gene Summary [Rat]
Predicted to enable ABC-type iron-sulfur cluster transporter activity and protein homodimerization activity. Involved in intracellular iron ion homeostasis and negative regulation of reactive oxygen species biosynthetic process. Predicted to be located in mitochondrion. Predicted to be active in mitochondrial inner membrane. Human ortholog(s) of this gene implicated in X-linked sideroblastic anemia with ataxia. Orthologous to human ABCB7 (ATP binding cassette subfamily B member 7). [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 rat Abcb7 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
