Predicted to enable several functions, including enzyme binding activity; spectrin binding activity; and transmembrane transporter binding activity. Acts upstream of or within several processes, including erythrocyte development; iron ion homeostasis; and porphyrin-containing compound biosynthetic process. Located in cortical cytoskeleton; membrane; and spectrin-associated cytoskeleton. Is expressed in several structures, including central nervous system; embryo mesenchyme; heart; retina; and skeletal muscle. Used to study hereditary spherocytosis type 1 and malaria. Human ortholog(s) of this gene implicated in anemia; hereditary spherocytosis; and hereditary spherocytosis type 1. Orthologous to human ANK1 (ankyrin 1).
