Cartee, Ann Arbor, United States. In Am J Physiol Endocrinol Metab, Jan 2016

Rab GAPs AS160 and Tbc1d1 play non-redundant roles in the regulation of glucose and energy homeostasis in mice.
Keller et al., Virginia, South Africa. In Am J Physiol Endocrinol Metab, Jan 2016

Roles of TBC1D1 and TBC1D4 in insulin- and exercise-stimulated glucose transport of skeletal muscle.
Cartee, Ann Arbor, United States. In Diabetologia, 2015
This review focuses on two paralogue Rab GTPase activating proteins known as TBC1D1 Tre-2/BUB2/cdc 1 domain family (TBC1D) 1 and TBC1D4 (also called Akt Substrate of 160 kDa, AS160) and their roles in controlling skeletal muscle glucose transport in response to the independent and combined effects of insulin and exercise.
Diabetes Alters the Expression and Translocation of the Insulin-Sensitive Glucose Transporters 4 and 8 in the Atria.
Lacombe et al., Oklahoma City, United States. In Plos One, 2014
Upon insulin stimulation, we reported an increase in Akt (Th308 and s473 sites) and AS160 phosphorylation, which was positively (P<0.05)
A common Greenlandic TBC1D4 variant confers muscle insulin resistance and type 2 diabetes.
Hansen et al., Copenhagen, Denmark. In Nature, 2014
Using array-based genotyping and exome sequencing, we discovered a nonsense p.Arg684Ter variant (in which arginine is replaced by a termination codon) in the gene TBC1D4 with an allele frequency of 17%.
Metabolism and insulin signaling in common metabolic disorders and inherited insulin resistance.
Højlund, Odense, Denmark. In Dan Med J, 2014
Insulin in physiological concentrations stimulates glucose uptake in human skeletal muscle in vivo by activation of the insulin signaling cascade to glucose transport through the enzymes IRS1, PI3K, Akt2, AS160/TBC1D4 and RAC1, and to glycogen synthesis through Akt2, inhibition of GSK3 and activation of glycogen synthase (GS) via dephosphorylation of serine residues in both the NH2-terminal (site 2+2a) and the COOH-terminal end (site 3a+3b).
ATP signaling in skeletal muscle: from fiber plasticity to regulation of metabolism.
Jaimovich et al., Santiago, Chile. In Exerc Sport Sci Rev, 2014
Tetanic electrical stimulation releases adenosine triphosphate (ATP) from muscle fibers through pannexin-1 channels in a frequency-dependent manner; extracellular ATP activates signals that ultimately regulate gene expression and is able to increase glucose transport through activation of P2Y receptors, phosphatidylinositol 3-kinase, Akt, and AS160.
Mechanisms in exercise-induced increase in glucose disposal in skeletal muscle.
Goyaram et al., Cape Town, South Africa. In Med Sport Sci, 2013
Evidence is provided that these signaling pathways converge with the insulin signaling cascade at: (a) aPKC (atypical protein kinase C), which signals via GTPases to remodel microtubules along which GLUT4-containing vesicles translocate, and (b) AS160 (a 160-kDa Akt substrate that has Rab-GTPase activity) to activate microtubule motor kinesin proteins that power vesicle translocation.
The association of ClipR-59 protein with AS160 modulates AS160 protein phosphorylation and adipocyte Glut4 protein membrane translocation.
Du et al., Boston, United States. In J Biol Chem, 2012
Because ClipR-59 also interacts with Akt and enhances the interaction between Akt and AS160, we suggest that ClipR-59 functions as a scaffold protein to facilitate Akt-mediated AS160 phosphorylation, thereby regulating glucose transport

Loffing et al., Zürich, Switzerland. In Histochem Cell Biol, 2012
TBC1D4 may play an important role for the control of renal ion and water handling and hence for the control of extracellular fluid homeostasis.

Sakamoto et al., Dundee, United Kingdom. In Cell Metab, 2011
