Also known as: Pik4ca; PI4K-alpha
Summary: Enables 1-phosphatidylinositol 4-kinase activity. Predicted to be involved in several processes, including phosphatidylinositol phosphate biosynthetic process; phosphatidylinositol-mediated signaling; and reorganization of cellular membranes to establish viral sites of replication. Predicted to act upstream of or within phosphorylation. Located in Golgi-associated vesicle membrane. 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, Dec 2024]
Expression: Biased expression in Brain (RPKM 204.2), Kidney (RPKM 119.1) and 9 other tissues See more

What's a GeneRIF?

palmitoylation is critical for targeting PI4KIIalpha to the trans-Golgi network and for enhancement of its association with low buoyant density membrane fractions
Title: Palmitoylation controls the catalytic activity and subcellular distribution of phosphatidylinositol 4-kinase II{alpha}.
These experiments suggest the participation of PI4K230 in a DNase and RNase sensitive complex with a unique localization and function in the nucleolus.
Title: Nucleolar localization of phosphatidylinositol 4-kinase PI4K230 in various mammalian cells.

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.
