P46934 | Q12809 | 1 | ubiquitination | down-regulates quantity by destabilization | 0.268 | We have previously shown that the E3 ubiquitin (Ub) ligase Nedd4-2 (neural precursor cell expressed developmentally down-regulated protein 4-2) targets the PY motif of hERG channels to initiate channel degradation. Although both immature and mature hERG channels contain the PY motif, Nedd4-2 selectively mediates the de... | SIGNOR-260998 |

P51812 | P18848 | 1 | phosphorylation | up-regulates | 0.633 | Here, we show that rsk2 is required for osteoblast differentiation and function. We identify the transcription factor atf4 as a critical substrate of rsk2 that is required for the timely onset of osteoblast differentiation, for terminal differentiation of osteoblasts, and for osteoblast-specific gene expression | SIGNOR-124436 |
Q9Y4X5 | Q13618 | 2 | binding | up-regulates activity | 0.314 | Here, we provide evidence that Ariadne RBR E3 ubiquitin ligases such as TRIAD1 and HHARI can bind and be activated by CRL complexes. Whereas TRIAD1 specifically associates with CUL5–RBX2, HHARI is more promiscuous towards cullin types and associates with RBX1-associated cullins 1, 2, 3, and 4A. Interestingly, both TRIA... | SIGNOR-268846 |
