Itpka Gene Summary [Mouse]
Predicted to enable kinase activity and small GTPase binding activity. Acts upstream of or within inositol metabolic process and regulation of synaptic plasticity. Predicted to be located in cytoskeleton and dendritic spine. Predicted to be active in several cellular components, including glutamatergic synapse; nucleus; and postsynaptic actin cytoskeleton. Orthologous to human ITPKA (inositol-trisphosphate 3-kinase A). [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 Itpka often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
