25886792 PI4K III alpha plays a role in biosynthetic trafficking of two different classes of proteins from the ER to the Golgi complex.
25855803 Missense mutations in PI4KA are associated with perisylvian polymicrogyria, cerebellar hypoplasia and arthrogryposis.
25608530 Our results suggest a plasticity of the molecular interactions that control PI4KIIIalpha localization and functions at the plasma membrane.
25209194 PI4KA and GRM3 polymorphisms have potential to jointly modulate antipsychotic response
25168678 our results suggest a mechanism of PI4K IIalpha recruitment, regulation, and function at the membrane.
24920820 The N-terminal 1,152 amino acids were dispensable for hepatitis C virus replication, phosphatidylinositol 4-phosphate induction, and enzymatic function, thereby defining the minimal PI4KIIIalpha core enzyme at a size of ca. 108 kDa.
24671493 These results suggest that type II PtdIns 4-kinases are part of piperine-mediated anti-inflammatory signaling mechanisms
24415756 PI4KA is essential for the maintenance of plasma membrane phosphatidylinositol 4,5-bisphosphate pools but only during strong stimulation of receptors coupled to phospholipase C activation.
24393405 PI4KA mRNA could be used as a new molecular marker to improve established prognostic models for hepatocellular carcinoma.
24077433 Descriptive Statement The genetic interactions associated with ILVatrophy rate in this study may be mapping variants inSYNJ2andPI4KAthat interact to decrease synthesisof PIP.
23675303 we demonstrate that PI4KIIIalpha activity affects the NS5A phosphorylation status.
22896614 Cell culture studies with Phosphatidylinositol-4-kinase IIIalpha inhibitors demonstrated that the kinase activity was essential for hepatitis C virus RNA replication.
22535966 Phosphatidylinositol 4-kinase IIalpha is palmitoylated by Golgi-localized palmitoyltransferases in cholesterol-dependent manner
22022594 PI4KA is necessary for the local enrichment of PI 4-phosphate at the hepatitis c virus membranous web.
21697487 These results suggest that hepatitis C virus NS5A modulation of PI4KA-dependent phosphatidylinositol 4-phosphate production influences replication complex formation.
21601653 confirmed the high copy number of PI4KIIIalpha transcript in K562 cells along with several genes located in the same region in Chr22, including two pseudogenes that cover most exons coding for isoform 1, consistent with chromosome amplification
21330372 Study identify the molecular chaperone Hsp90 as a binding partner of PI4KIIbeta, but not of PI4KIIalpha.
21297162 PI4KIIIalpha is an essential host factor that supports HCV proliferation and therefore PI4KIIIalpha may be a legitimate target for anti-HCV therapy.
21238945 This analysis suggests that the direct activation of a lipid kinase PI4KA by hepatitis C virus NS5A contributes critically to the integrity of the membranous viral replication complex.
20628086 Observational study of gene-disease association, gene-environment interaction, and pharmacogenomic / toxicogenomic. (HuGE Navigator)
20530568 Data suggest that Rab1 contributes to the specificity and timing of GBF1 recruitment by activating PI4KIIIalpha, and that the PtdIns(4)P produced then allows GBF1 to bind to Golgi membranes and activate Arf1.
20052689 No strong association between PIK4CA and psychosis in people with 22q11.2 deletion syndrome
19913121 Observational study of gene-disease association. (HuGE Navigator)

18646052 Observational study of gene-disease association. (HuGE Navigator)
18615484 Failure to confirm the association between the PIK4CA gene and schizophrenia in a Japanese population is reported.
18585705 The putative bipartite nuclear localization signal(NLS) itself is a nucleolar targeting signal, and for nuclear import PI4K230 requires a larger sequence around it or, alternatively, the monopartite NLS.
18521859 The present study suggests that the PIK4CA gene does not play a significant role in the vulnerability to METH use disorder in the Japanese population.
18521859 Observational study of gene-disease association. (HuGE Navigator)
18077555 These results indicate that a small fraction of the cellular PI4K activity is sufficient to maintain plasma membrane phosphoinositide pools.
17893707 The PIK4CA gene is located in the chromosome 22q11 deletion syndrome region, which is of particular interest because it has been implicated in schizophrenia.
17893707 Observational study of gene-disease association. (HuGE Navigator)
17555516 PI4KIIalpha or PI4KIIbeta knockdown, but not type III PI4Kbeta knockdown, inhibits Listeria internalization.
17131383 These experiments suggest the participation of PI4K230 in a DNase and RNase sensitive complex with a unique localization and function in the nucleolus.
16606619 nuclear phosphatidylinositol 4-phosphate, and consequently, synthesis of polyphosphoinositides are required for a correct nuclear function
15634669 PI4KIIIbeta (PIK4CB) and PI4KIIalpha (PIK4CA) localize to discrete subcompartments of the Golgi complex in Madin-Darby canine kidney (MDCK) cells.
