Predicted to enable actin filament binding activity. Predicted to be involved in actin cytoskeleton organization. Predicted to act upstream of or within several processes, including lymphocyte homeostasis; porphyrin-containing compound biosynthetic process; and positive regulation of T cell proliferation. Located in axon and cytoplasmic side of plasma membrane. Human ortholog(s) of this gene implicated in hereditary spherocytosis and hereditary spherocytosis type 3. Orthologous to human SPTA1 (spectrin alpha, erythrocytic 1). [provided by Alliance of Genome Resources, Apr 2022]
