Abstract

Patched (Ptc), the main receptor for Sonic Hedghog, is a tumor suppressor. Ptc has been shown to be a dependence receptor, and as such triggers apoptosis in the absence of its ligand. This apoptosis induction occurs through the recruitment by the Ptc intracellular domain of a caspase-activating complex, which includes the adaptor proteins DRAL and TUCAN, and the apical caspase-9. We show here that this caspase-activating complex also includes the E3 ubiquitin ligase NEDD4. We demonstrate that Ptc-mediated apoptosis and Ptc-induced caspase-9 activation require NEDD4. We show that Ptc, but not Bax, the prototypical inducer of the intrinsic cell-death pathway, triggers polyubiquitination of caspase-9. Moreover, a caspase-9 mutant that could not be ubiquitinated failed to mediate Ptc-induced apoptosis. Taken together, these data support the view that the Ptc dependence receptor specifically allows the activation of caspase-9 via its ubiquitination, which occurs via the recruitment by Ptc of NEDD4.

  • In absence of ligands, PTCH1 interacts with FHL2, favoring assembly of CASP9-activating complex consisting of CARD8 and NEDD4.

    “(2) PTCH1 interacts with the cytosolic adaptor four and a half LIM domains 2 (FHL2; best known as DRAL), hence favoring the assembly of a CASP9-activating complex consisting of caspase recruitment domain family member 8 (CARD8; also known as TUCAN) and neural precursor cell expressed, developmentally down-regulated 4, E3 ubiquitin protein ligase (NEDD4) [352–354]”

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.
