Abstract

Tumor necrosis factor receptor-associated factor 6 (TRAF6), the crucial adaptor molecule of receptor activator of NF-kappaB (RANK), plays an essential role in governing the formation of multi-nucleated osteoclasts. TRAF6 is a RING-dependent ubiquitin (Ub) ligase that in conjunction with Ubc13/Uev1A catalyzes its own auto-ubiquitination via Lys63-linked poly-Ub chains. While the receptor-adaptor function of TRAF6 in RANK signaling is well understood, the significance of its Ub ligase activity in this process remains largely unknown. In this study, we show that retroviral expression of TRAF6, but not a RING mutant of TRAF6 was able to rescue TRAF6-deficient monocytes for the activation of IKK and osteoclast differentiation by RANKL. Furthermore, a catalytically inactive Ubc13 or stable knockdown of Ubc13 significantly prevents RANK-mediated TRAF6 ubiquitination and NF-kappaB and JNK activation. These data establish a signaling cascade in which regulated Lys63-linked TRAF6 auto-ubiquitination is the critical upstream mediator of osteoclast differentiation.

  • The RANKL-activated kinase cascade requires Lys63-linked TRAF-6 auto-ubiquitination and initiates transcription of AP-1, c-Fos, NF-κB, and NFATc1, the master regulator of osteoclast differentiation.

    “This cascade requires Lys63-linked TRAF-6 auto-ubiquitination [22] and initiates the transcription of activator protein-1 (AP-1), c-Fos, NF-κB, and nuclear factor of activated T cells cytoplasmic calcineurin-dependent 1 (NFATc1), the master regulator of osteoclast differentiation [20,23,24].”

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.
