Abstract

PURPOSE OF REVIEW: Glucokinase regulator (GCKR) encodes glucokinase regulatory protein (GKRP), a hepatocyte-specific inhibitor of the glucose-metabolizing enzyme glucokinase (GCK). Genome-wide association studies have identified a common coding variant within GCKR associated with multiple metabolic traits. This review focuses on recent insights into the critical role of GKRP in hepatic glucose metabolism that have stemmed from the study of human genetics. This knowledge has improved our understanding of glucose and lipid physiology and informed the development of targeted molecular therapeutics for diabetes. RECENT FINDINGS: Rare GCKR variants have effects on GKRP expression, localization, and activity. These variants are collectively associated with hypertriglyceridaemia but are not causal. Crystal structures of GKRP and the GCK-GKRP complex have been solved, providing greater insight into the molecular interactions between these proteins. Finally, small molecules have been identified that directly bind GKRP and reduce blood glucose levels in rodent models of diabetes. SUMMARY: GCKR variants across the allelic spectrum have effects on glucose and lipid homeostasis. Functional analysis has highlighted numerous molecular mechanisms for GKRP dysfunction. Hepatocyte-specific GCK activation via small molecule GKRP inhibition may be a new avenue for type 2 diabetes treatment, particularly considering evidence indicating GKRP loss-of-function alone does not cause hypertriglyceridaemia.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The liver/lipid cluster includes loci GCKR, PNPLA3, and TM6SF2, which functional experiments have shown to relate to liver lipid metabolism.

    “The liver/lipid cluster includes loci GCKR, PNPLA3, and TM6SF2, which have been shown through functional experiments to relate to liver lipid metabolism (24–31).”

    From Increased genetic risk for β-cell failure is associated with β-cell function decline in people with prediabetes (2024) · cites this paper as [28]

    The Conclusion (page not provided) links GCKR’s gene product, GKRP, to hepatic triglyceride metabolism and reports functional analyses of its activity. The paper does not establish the claimed liver/lipid cluster or address PNPLA3 and TM6SF2, so it supports only the GCKR portion of the sentence. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
