About PI4KB

Cytogenetic location: 1q21.3 Genomic coordinates (GRCh38): 1:151,291,797-151,327,715 (from NCBI)

This gene has 13 transcripts (splice variants), 213 orthologues and 9 paralogues. Ubiquitous expression in thyroid (RPKM 18.9), testis (RPKM 17.6) and 25 other tissues.

Summary

Enables 1-phosphatidylinositol 4-kinase activity and 14-3-3 protein binding activity. Predicted to be involved in phosphatidylinositol phosphate biosynthetic process and phosphatidylinositol-mediated signaling. Located in Golgi membrane. [provided by Alliance of Genome Resources, Apr 2022]
