TANGO1/cTAGE5 receptor as a polyvalent template for assembly of large COPII coats

Open access

Abstract

Significance: Proteins destined for secretion from cells enter the secretory pathway in coat protein complex II (COPII)-coated vesicles budding from the endoplasmic reticulum (ER). Most cargo proteins are small and exit the ER in 60-nm vesicles. However, some secretory cargos are too large to enter such carriers; in particular, the procollagen precursor of the extracellular matrix exits the ER as a 300- to 400-nm fibril. Recent research suggests that procollagen may be packaged into large COPII-coated tubules, guided by the receptor molecule TANGO1/cTAGE5. We show that each TANGO1/cTAGE5 receptor protein has a multiplicity of binding sites to recruit and concentrate COPII proteins. We propose the model that TANGO1/cTAGE5 instructs the COPII coat to form large tubular carriers.

  • The model of the Sec23-Grh1 complex contains an interface between the Sec23 gelsolin domain and the PPP motif of Grh1, and an interface between the Grh1 IDR and Sec23 involving a disorder-to-helical transition.

    “Our model of the Sec23–Grh1 complex contains an interface between the Sec23 gelsolin domain and the PPP motif of Grh1 (80), and an interface between the Grh1 IDR and Sec23 involving a disorder-to-helical transition (fig. S25C).”

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.
