TBC proteins: GAPs for mammalian small GTPase Rab?

Fukuda, Mitsunori·2011·Bioscience Reports

Abstract

The TBC (Tre-2/Bub2/Cdc16) domain was originally identified as a conserved domain among the tre-2 oncogene product and the yeast cell cycle regulators Bub2 and Cdc16, and it is now widely recognized as a conserved protein motif that consists of approx. 200 amino acids in all eukaryotes. Since the TBC domain of yeast Gyps [GAP (GTPase-activating protein) for Ypt proteins] has been shown to function as a GAP domain for small GTPase Ypt/Rab, TBC domain-containing proteins (TBC proteins) in other species are also expected to function as a certain Rab-GAP. More than 40 different TBC proteins are present in humans and mice, and recent accumulating evidence has indicated that certain mammalian TBC proteins actually function as a specific Rab-GAP. Some mammalian TBC proteins {e.g. TBC1D1 [TBC (Tre-2/Bub2/Cdc16) domain family, member 1] and TBC1D4/AS160 (Akt substrate of 160 kDa)} play an important role in homoeostasis in mammals, and defects in them are directly associated with mouse and human diseases (e.g. leanness in mice and insulin resistance in humans). The present study reviews the structure and function of mammalian TBC proteins, especially in relation to Rab small GTPases.

  • The TBC1D7 apo structure reveals an architecture highly conserved with other TBC domain proteins, with little conformational difference in comparison to the TSC1-complexed structures.

    “The apo structure (Fig. 5D) reveals an architecture highly conserved with other TBC domain proteins (Fischer et al., 2016; Fukuda, 2011; Park et al., 2011), with little conformational difference in comparison to the TSC1-complexed structures.”

  • Unlike other TBC proteins, TBC1D7 does not appear to have GAP activity relevant to the Rheb signaling axis upstream of mTORC1, instead likely increasing the sensitivity and responsivity of the entire complex to environmental signals.

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.
