Impa2 Gene Summary [Mouse]
Predicted to enable inositol monophosphate 1-phosphatase activity and protein homodimerization activity. Predicted to be involved in inositol metabolic process; response to lithium ion; and signal transduction. Predicted to be located in cytoplasm. Is expressed in several structures, including alimentary system; genitourinary system; hemolymphoid system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in bipolar disorder and schizophrenia. Orthologous to human IMPA2 (inositol monophosphatase 2). [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 mouse Impa2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
