Abstract:
Type 2 phosphatidylinositol-5-phosphate 4-kinase (PI5P4K) converts phosphatidylinositol-5-phosphate to phosphatidylinositol-4,5-bisphosphate. Mammals have three enzymes PI5P4Kα, PI5P4Kβ, and PI5P4Kγ, and these enzymes have been implicated in metabolic control, growth control, and a variety of stress responses. Here, we show that mice with germline deletion of type 2 phosphatidylinositol-5-phosphate 4-kinase gamma (Pip4k2c), the gene encoding PI5P4Kγ, appear normal in regard to growth and viability but have increased inflammation and T-cell activation as they age.

Abstract:
The kinase complex mechanistic target of rapamycin 1 (mTORC1) plays an important role in controlling growth and metabolism. We report here that the stepwise formation of phosphatidylinositol 3-phosphate (PI(3)P) and phosphatidylinositol 3,5-bisphosphate (PI(3,5)P2) regulates the cell type–specific activation and localization of mTORC1. PI(3)P formation depends on the class II phosphatidylinositol 3-kinase (PI3K) PI3K-C2α, as well as the class III PI3K Vps34, while PI(3,5)P2 requires the phosphatidylinositol-3-phosphate-5-kinase PIKFYVE. In this paper, we show that PIKFYVE and PI3K-C2α are nece

Abstract:
Substitution of phenylalanine for tyrosine at codon 809 (Y809F) of the human colony-stimulating factor 1 (CSF-1) receptor (CSF-1R) impairs ligand-stimulated tyrosine kinase activity, prevents induction of c-MYC and cyclin D1 genes, and blocks CSF-1-dependent progression through the G1 phase of the cell cycle. We devised an unbiased genetic screen to isolate genes that restore the ability of CSF-1 to stimulate growth in cells that express mutant CSF-1R (Y809F). This screen led us to identify a truncated form of the murine type Ibeta phosphatidylinositol 4-phosphate 5-kinase (mPIP5K-Ibeta). This

Abstract:
Lipid kinases are central players in lipid signaling pathways involved in inflammation, tumorigenesis, and metabolic syndrome. A number of these kinase targets have proven difficult to investigate in higher throughput cell-free assay systems. This challenge is partially due to specific substrate interaction requirements for several of the lipid kinase family members and the resulting incompatibility of these substrates with most established, homogeneous assay formats. Traditional, cell-free in vitro investigational methods for members of the lipid kinase family typically involve substrate inco

Hyperosmotic stress increases phosphoinositide levels, reorganizes the actin cytoskeleton, and induces multiple acute and adaptive physiological responses.

Depletion of the human type I phosphatidylinositol 4-phosphate 5-kinase β isoform (PIP5KIβ) by RNA interference impaired both the PIP2 and actin cytoskeletal responses.

Abstract:
During the late stages of the HIV-1 replication cycle, the viral polyprotein Pr55Gag is recruited to the plasma membrane (PM), where it binds phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) and directs HIV-1 assembly. We show that Rab27a controls the trafficking of late endosomes carrying phosphatidylinositol 4-kinase type 2 α (PI4KIIα) toward the PM of CD4+ T cells. Hence, Rab27a promotes high levels of PM phosphatidylinositol 4-phosphate and the localized production of PI(4,5)P2, therefore controlling Pr55Gag membrane association. Rab27a also controls PI(4,5)P2 levels at the virus-containi

Type I PIP kinases (phosphatidylinositol 4-phosphate 5-kinases, PIP5Ks) catalyse the majority of cellular synthesis of PI(4,5)P2. To date, three mammalian isoforms (r1, r2, r3) have been found. PIP5KIr is subject to complex C-terminal splice variation, enhancing its transcriptional diversity through evolution and producing at least 5 known spliceoforms in the mammals.
