Ppip5k2 Gene Summary [Mouse]
Enables 5-diphosphoinositol pentakisphosphate 1-kinase activity and inositol hexakisphosphate kinase activity. Predicted to be involved in inositol metabolic process and inositol phosphate biosynthetic process. Predicted to be active in cytosol. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; salivary gland primordium; and sensory organ. Used to study keratoconus and nonsyndromic deafness. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 100. Orthologous to human PPIP5K2 (diphosphoinositol pentakisphosphate kinase 2). [provided by Alliance of Genome Resources, Apr 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 Ppip5k2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
