P36897 | O43541 | 0 | binding | down-regulates activity | 0.74 | The inhibitory Smads (I-Smads), i.e. Smad6 and Smad7, are negative regulators of transforming growth factor-_ (TGF-_) family signaling. I-Smads inhibit TGF-_ family signaling principally through physical interaction with type I receptors (activin receptor-like kinases), so as to compete with receptor-regulated Smads (R-Smads) for activation. | SIGNOR-167160 |
P19838 | P25963 | 0 | binding | down-regulates activity | 0.74 | Nf-kappa b is an inducible transcription factor comprised of a 50-kd (p50) and a 65-kd (p65) subunit. Induction of nf-kappa b activity, which is a critical event in many signal transduction pathways, involves release from a cytoplasmic inhibitory protein, i kappa b, followed by translocation of the active transcription factor complex into the nucleus. we demonstrate by in vitro and in vivo methods that the recently cloned i kappa b/mad-3 interacts with both the p50 and p65 subunits of nf-kappa b | SIGNOR-17688 |
Q7L523 | Q8N8N0 | 0 | polyubiquitination | down-regulates activity | 0.74 | Here, we identified the lysosome-anchored E3 ubiquitin ligase RNF152 as an essential negative regulator of the mTORC1 pathway by targeting RagA for K63-linked ubiquitination. RNF152 interacts with and ubiquitinates RagA in an amino-acid-sensitive manner. The mutation of RagA ubiquitination sites abolishes this effect of RNF152 and enhances the RagA-mediated activation of mTORC1. Ubiquitination by RNF152 generates an anchor on RagA to recruit its inhibitor GATOR1, a GAP complex for Rag GTPases. | SIGNOR-272222 |
P56645 | P49674 | 0 | phosphorylation | down-regulates activity | 0.74 | The CKI phosphorylation of mPer1 and mPer3 proteins results in their rapid degradation, which is dependent on the ubiquitin-proteasome pathway. Moreover, CKIepsilon and CKIdelta are able to induce nuclear translocation of mPer3, which requires its nuclear localization signal. The mutation in potential phosphorylation sites on mPer3 decreased the extent of both nuclear translocation and degradation of mPer3 that are stimulated by CKIepsilon. | In mut7 in which all of the conserved serine and threonine residues in this region were mutated, the ratio of the shifted band was greatly reduced reproducibly. | SIGNOR-250816 |

Furthermore, we observed that the phosphorylation of Tyr221 of CrkII correlated with its dissociation from the EGF receptor, implicating the phosphorylation of Tyr221 in the negative feedback of binding to the EGF receptor. | SIGNOR-251091 |
