Abstract

TBC1D1 (tre-2/USP6, BUB2, cdc16 domain family member 1) is a Rab-GAP (GTPase-activating protein) that is highly expressed in skeletal muscle, but little is known about TBC1D1 regulation and function. We studied TBC1D1 phosphorylation on three predicted AMPK (AMP-activated protein kinase) phosphorylation sites (Ser231, Ser660 and Ser700) and one predicted Akt phosphorylation site (Thr590) in control mice, AMPKα2 inactive transgenic mice (AMPKα2i TG) and Akt2-knockout mice (Akt2 KO). Muscle contraction significantly increased TBC1D1 phosphorylation on Ser231 and Ser660, tended to increase Ser700 phosphorylation, but had no effect on Thr590. AICAR (5-aminoimidazole-4-carboxyamide ribonucleoside) also increased phosphorylation on Ser231, Ser660 and Ser700, but not Thr590, whereas insulin only increased Thr590 phosphorylation. Basal and contraction-stimulated TBC1D1 Ser231, Ser660 and Ser700 phosphorylation were greatly reduced in AMPKα2i TG mice, although contraction still elicited a small increase in phosphorylation. Akt2 KO mice had blunted insulin-stimulated TBC1D1 Thr590 phosphorylation. Contraction-stimulated TBC1D1 Ser231 and Ser660 phosphorylation were normal in high-fat-fed mice. Glucose uptake in vivo was significantly decreased in tibialis anterior muscles overexpressing TBC1D1 mutated on four predicted AMPK phosphorylation sites. In conclusion, contraction causes site-specific phosphorylation of TBC1D1 in skeletal muscle, and TBC1D1 phosphorylation on AMPK sites regulates contraction-stimulated glucose uptake. AMPK and Akt regulate TBC1D1 phosphorylation, but there must be additional upstream kinases that mediate TBC1D1 phosphorylation in skeletal muscle.

  • In response to muscle contractions, increases in TBC1D1 phosphorylation are important for 14-3-3 binding, inhibition of GAP domain function and subsequent increases in glucose uptake.

    “In response to muscle contractions, increases in TBC1D1 phosphorylation are important for 14-3-3 binding, inhibition of GAP domain function and subsequent increases in glucose uptake [95,102].”

    From AMPK and Exercise: Glucose Uptake and Insulin Sensitivity (2013) · cites this paper as [102]

  • TBC1D1 is phosphorylated in response to AICAR and muscle contractions/exercise.

    “Like TBC1D4, TBC1D1 is phosphorylated in response to AICAR and muscle contractions/exercise [74,95,101,102,117].”

    From AMPK and Exercise: Glucose Uptake and Insulin Sensitivity (2013) · cites this paper as [102]

  • Muscle contractions/exercise predominantly induces TBC1D1 phosphorylation on S231 in both humans and mice.

    “AMPK phosphorylates multiple sites on TBC1D1 (S231, S499, T590, S660, S700), and muscle contractions/exercise predominately induces TBC1D1 phosphorylation on S231 in both humans and mice [74,102,117].”

    From AMPK and Exercise: Glucose Uptake and Insulin Sensitivity (2013) · cites this paper as [102]

  • Inactivating 4 predicted TBC1D1 phosphorylation sites (4P mutant) results in 25% to 30% reduction in contraction-mediated glucose uptake.

    “Interestingly, two separate studies inactivating 4 predicated TBC1D1 phosphorylation sites (4P mutant) results in 25% to 30% reduction in contraction-mediated glucose uptake [95,102].”

    From AMPK and Exercise: Glucose Uptake and Insulin Sensitivity (2013) · cites this paper as [102]

  • TBC1D1 expression is reduced by ~50% in skeletal muscle of AMPK α2 KO, α2 KD, α2iTg and β1β2 M-KO mice.

    “In contrast, TBC1D1 expression is reduced by ~50% in skeletal muscle of AMPK α2 KO, α2 KD, α2iTg and β1β2 M-KO mice [30,74,102,117], and this may be compensatory for the lack of phosphorylation and inhibition by AMPK, or alternatively, reduced muscle glucose uptake in AMPK β1β2 M-KO mice.”

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.
