We show that the aberrantly increased PP2A in lupus T cells dephosphorylates Elf-1 at Thr-231. Dephosphorylation results in limited expression and binding of the 98 kDa Elf-1 form to the CD3zeta and FcRgamma promoters. Suppression of the expression of the PP2A leads to increased expression of CD3zeta and decreased expression of FcRgamma genes and correction of the early signaling response | SIGNOR-248591 |

P0DTC5 | Q7Z434 | 1 | binding | down-regulates activity | 0.1 | Here, we identified SARS-CoV-2 membrane glycoprotein M as a negative regulator of the innate immune response. We found that the M protein interacted with the central adaptor protein MAVS in the innate immune response pathways. This interaction impaired MAVS aggregation and its recruitment of downstream TRAF3, TBK1, and IRF3, leading to attenuation of the innate antiviral response. Our findings reveal a mechanism by which SARS-CoV-2 evades the innate immune response and suggest that the M protein of SARS-CoV-2 is a potential target for the development of SARS-CoV-2 interventions. | SIGNOR-262515 |

Q13480 | Q06124 | 0 | dephosphorylation | down-regulates activity | 0.952 | These results suggest that Tyr(P)-627 and Tyr(P)-659 of Gab1 constitute a bisphosphoryl tyrosine-based activation motif (BTAM) that binds and activates SHP2.|Thus, physical association of activated SHP2 with Gab1 is necessary and sufficient to mediate the ERK mitogen-activated protein kinase activation. Phosphopeptides derived from Gab1 were dephosphorylated by active SHP2 in vitro. | SIGNOR-248674 |

Q9UHB9 | P09132 | 0 | binding | up-regulates activity | 0.95 | Mammalian SRP comprises the highly base-paired SRP RNA (also referred to as 7SL RNA) of ∼300 nt and six proteins (SRP9, SRP14, SRP19, SRP54, SRP68 and SRP72) (Figure (Figure1A).1A). The hierarchy of protein addition always starts with the scaffolding protein SRP19 (together with SRP9/14 for the entire SRP) followed by SRP68/72 and finally by SRP54. | SIGNOR-261167 |
Q13618 | Q14145 | 0 | binding | up-regulates activity | 0.95 | Keap1 is a BTB-Kelch protein that functions as a substrate adaptor protein for a Cul3-dependent E3 ubiquitin ligase complex. Keap1 targets its substrate, the Nrf2 transcription factor, for ubiquitination and subsequent degradation by the 26 S proteasome. The N-terminal BTB domain and central linker region of Keap1 bind Cul3, whereas the C-terminal Kelch domain of Keap1 binds Nrf2 via residues located within loops that extend out from the bottom of the Kelch domain | SIGNOR-268925 |
P60880 | P21579 | 0 | binding | up-regulates activity | 0.95 | Because synaptotagmins bind SNAP-25 and Ca2+, SNAP-25 has also been linked to the Ca2+ dependence of exocytosis (42). One model suggests that synaptotagmin blocks full SNARE fusion pore formation by binding to t-SNAREs.This interaction prevents fusion from occurring in the absence of calcium. When Ca2+ is present, synaptotagmin releases the t-SNAREs so they can fully zipper with the v-SNARE, leading to fusion | SIGNOR-263975 |

P08151 | Q9UMX1 | 0 | binding | down-regulates activity | 0.949 | Here we characterize structural and functional determinants of Su(fu) required for Gli regulation and show that Su(fu) contains at least two distinct domains: a highly conserved carboxy-terminal region required for binding to the amino-terminal ends of the Gli proteins and a unique amino-terminal domain that binds the carboxy-terminal tail of Gli1. While each domain is capable of binding to different Gli1 regions independently, interactions between Su(fu) and Gli1 at both sites are required for cytoplasmic tethering and repression of Gli1 | SIGNOR-249591 |
P00533 | P01133 | 0 | binding | up-regulates activity | 0.949 | Epidermal growth factor (egf) regulates cell proliferation and differentiation by binding to the egf receptor (egfr) extracellular region, comprising domains i-iv, with the resultant dimerization of the receptor tyrosine kinase. | SIGNOR-186159 |
P00734 | P01008 | 0 | cleavage | down-regulates activity | 0.948 | Antithrombin (AT), a member of the serine protease inhibitor (SERPIN) superfamily, is a major circulating inhibitor of blood coagulation proteases such as factor (F) IIa (known as thrombin), FXa and, to a lesser extent, FIXa, FXIa and FXIIa. SERPINC1, which encodes AT in humans, is located on chromosome 1q25.1 | SIGNOR-264136 |

Q06609 | P51587 | 0 | binding | up-regulates activity | 0.947 | We suggest that interactions of the BRCA2 C-terminal region with RAD51 may facilitate efficient nucleation of RAD51 multimers on DNA and thereby stimulate recombination-mediated repair. | SIGNOR-259905 |

P12830 | O60716 | 0 | binding | up-regulates quantity by stabilization | 0.947 | P120 regulates E-cadherin turnover at the cell membrane. Because direct binding of p120 to E-cadherin is required, it is possible that p120 binding blocks the interaction of an unknown binding partner (or event) that targets E-cadherin for degradation | SIGNOR-252123 |
P49768 | Q96BI3 | 0 | binding | up-regulates | 0.947 | By using co-immunoprecipitation and nickel affinity pull-down approaches, we now show that mammalian aph-1 (maph-1), a conserved multipass membrane protein, physically associates with nicastrin and the heterodimers of the presenilin amino- and carboxyl-terminal fragments in human cell lines and in rat brain. | SIGNOR-93262 |
Q8TAT6 | P55072 | 0 | binding | up-regulates activity | 0.946 | These findings ascribe specific functions to each of the components of the VCP-UFD1L-NPL4 complex in Vpu-mediated CD4 degradation: VCP energizes the process through ATP binding and hydrolysis, UFD1L binds ubiquitinated CD4 through recognition of K48 Ub chains, and NPL4 stabilizes UFD1L. VCP is thus likely to provide the energy required for extraction of CD4 from membranes. | SIGNOR-252423 |
P24530 | P05305 | 0 | binding | up-regulates | 0.946 | Endothelin-1 (et-1) and angiotensin ii (angii), two potent vasoactive peptides involved in the regulation of cardiovascular homeostasis, also induce mitogenic and pro-angiogenic responses in vitro and in vivo. Both peptides are produced by cleavage of inactive precursors by metalloproteases (endothelin-converting enzyme and angiotensin-converting enzyme, respectively) and activate two subtypes of membrane receptors (eta-r and etb-r for et-1, at1r and at2r for angii) that all belong to the superfamily of g-protein coupled receptors. | SIGNOR-145762 |
Q9NWZ3 | Q99836 | 0 | binding | up-regulates activity | 0.946 | Signaling between MyD88 and TRAF6 is mediated by members of the IL-1R-associated kinase (IRAK) family; however, the exact function of each IRAK protein remains controversial. IRAK-1 is required for the optimal transduction of IL-1R- and TLR-mediated signals, but IRAK-1 can be replaced by other IRAKs. Surprisingly, gene targeting studies show that the newest IRAK protein, IRAK-4, has an essential role in mediating signals initiated by IL-1R and TLR engagement. | SIGNOR-252097 |

UAF1 binding increases the catalytic turnover (kcat) but does not increase the affinity of the USP1 enzyme for the substrate (KM). | SIGNOR-263274 |
