Summary: Predicted to enable phosphotransferase activity, alcohol group as acceptor 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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
