P31749 | Q96S44 | 1 | phosphorylation | up-regulates | 0.297 | Here we show that such an activation of prpk is mediated by another kinase, akt/pkb, which phosphorylates prpk at ser250. | SIGNOR-252503 |
Q14457 | O95229 | 2 | binding | up-regulates activity | 0.435 | We show that Beclin-1 interacts directly with Zwint-1-a component of the KMN (KNL-1/Mis12/Ndc80) complex-which is essential for kinetochore-microtubule interactions. This suggests that Beclin-1 acts downstream of the KMN complex to influence the recruitment of outer kinetochore proteins and promotes accurate kinetochor... | SIGNOR-265027 |

P49841 | P24723 | 0 | phosphorylation | down-regulates | 0.2 | Gsk3 is different from most kinases in that it is constitutively partially active and the most common regulatory mechanism is inhibition by phosphorylation of ser21 in gsk3_ or ser9 in gsk3_. This inhibitory phosphorylation can be mediated by several kinases, such as akt/protein kinase b (pkb), protein kinase c (pkc) a... | SIGNOR-188585 |

Q76N32 | P53350 | 0 | phosphorylation | down-regulates quantity by destabilization | 0.44 | We show that the intercentrosomal linker protein Cep68 is degraded in prometaphase through the SCF(βTrCP) (Skp1-Cul1-F-box protein) ubiquitin ligase complex. Cep68 degradation is initiated by PLK1 phosphorylation of Cep68 on Ser 332, allowing recognition by βTrCP. | SIGNOR-275621 |
P49137 | Q07352 | 1 | phosphorylation | down-regulates | 0.62 | Mk2-mediated inhibition of brf1 requires phosphorylation at s54, s92, and s203. Phosphorylation of brf1 by mk2 does not appear to alter its ability to interact with ares or to associate with mrna decay enzymes. Thus, mk2 inhibits brf1-dependent amd through direct phosphorylation. | SIGNOR-161274 |
