Impa1 Gene Summary [Mouse]
Enables magnesium ion binding activity. Predicted to be involved in inositol metabolic process; phosphatidylinositol biosynthetic process; and signal transduction. Predicted to be located in axon; cytoplasm; and neuronal cell body. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and sensory organ. Human ortholog(s) of this gene implicated in autosomal recessive intellectual developmental disorder 59 and intellectual disability. Orthologous to human IMPA1 (inositol monophosphatase 1).

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 Impa1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
