Summary
Predicted to enable 1-phosphatidylinositol 4-kinase activity. Predicted to be involved in Golgi organization; endosome organization; and phosphatidylinositol phosphate biosynthetic process. Predicted to be located in bounding membrane of organelle; cytosol; and endoplasmic reticulum membrane. Predicted to be active in endosome; plasma membrane; and trans-Golgi network. Is expressed in embryo. Orthologous to human PI4K2B (phosphatidylinositol 4-kinase type 2 beta). [provided by Alliance of Genome Resources, Nov 2024]
Expression
Broad expression in placenta adult (RPKM 17.6), duodenum adult (RPKM 15.1) and 24 other tissues See more

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.
