Pi4ka Gene Summary [Mouse]
Enables 1-phosphatidylinositol 4-kinase activity. Involved in myelination in peripheral nervous system and phosphatidylinositol phosphate biosynthetic process. Acts upstream of or within Schwann cell migration and actin cytoskeleton organization. Predicted to be located in Golgi-associated vesicle membrane. Predicted to be active in cytoplasm and plasma membrane. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in hereditary spastic paraplegia 84. Orthologous to human PI4KA (phosphatidylinositol 4-kinase alpha). [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 Pi4ka often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
