Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

The p110 delta structure: mechanisms for selectivity and potency of new PI(3)K inhibitors. [PDF]

open access: yes, 2010
Deregulation of the phosphoinositide-3-OH kinase (PI(3)K) pathway has been implicated in numerous pathologies including cancer, diabetes, thrombosis, rheumatoid arthritis and asthma.

Phosphatidylinositol-4-phosphate 5-Kinase Isozymes Catalyze the Synthesis of 3-Phosphate-containing Phosphatidylinositol Signaling Molecules [PDF]

open access: yesJournal of Biological Chemistry, 1997
Phosphatidylinositol-4-phosphate 5-kinases (PIP5Ks) utilize phosphatidylinositols containing D-3-position phosphates as substrates to form phosphatidylinositol 3,4-bisphosphate. In addition, type I PIP5Ks phosphorylate phosphatidylinositol 3, 4-bisphosphate to phosphatidylinositol 3,4,5-trisphosphate, while type II kinases have less activity toward ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Adipocyte-specific deletion of PIP5K1c reduces diet-induced obesity and insulin resistance by increasing energy expenditure

open access: yesLipids in Health and Disease, 2022
Background Phosphatidylinositol 4-phosphate 5-kinase type I c (PIP5K1c) catalyses the synthesis of phospholipid phosphatidylinositol 4,5-bisphosphate (PIP2) by phosphorylating phosphatidylinositol 4 phosphate, which plays multiple roles in regulating ...

Capsaicin protects neuromuscular junctions from the inhibitory effects of botulinum neurotoxin A [PDF]

open access: yes, 2008
Within 24 hrs after injecting botulinum neurotoxin A (BoNT/A) into the hindlimb, mice lost the toe spread reflex and developed progressive muscle weakness. At the same time, the compound muscle action potential amplitude decreased. Injection of capsaicin

Mechanism of NaCl transport-stimulated prostaglandin formation in MDCK cells [PDF]

open access: yes, 1987
Recently we have found that stimulation of NaCl transport in high-resistance MDCK cells enhances their prostaglandin formation. In the present study, we investigated the mechanisms by which prostaglandin formation could be linked to the ion transport in ...

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

open access: yesMolecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

Distinct functional properties of two electrogenic isoforms of the SLC34 Na‐Pi cotransporter

open access: yesPhysiological Reports, 2019
Inorganic phosphate (Pi) is crucial for proper cellular function in all organisms. In mammals, type II Na‐Pi cotransporters encoded by members of the Slc34 gene family play major roles in the maintenance of Pi homeostasis.

Stimulation of glucose utilization in 3T3 adipocytes and rat diaphragm in vitro by the sulphonylureas, glimepiride and glibenclamide, is correlated with modulations of the cAMP regulatory cascade [PDF]

open access: yes, 1994
The long-term hypoglycemic activity of sulphonylurea drugs has been attributed, in part at least, to the stimulation of glucose utilization in extra-pancreatic tissues. The novel sulphonylurea, glimepiride, gives rise to a longer lasting reduction in the
