F-box/WD repeat-containing protein 7 - FBXW7 -  Homo sapiens
TRG_NLS_MonoCore_21015BinaryPre‑translationalAlternative splicing removes the nuclear localisation signal (NLS) of F-box/WD repeat-containing protein 7 (FBXW7), abrogating binding to Importin subunit alpha-1 (KPNA1). There are two other NLS motifs in the protein, meaning the isoform can still enter the nucleus.

DOC_WW_Pin1_4202207BinaryPhysicochemical compatibilityPhosphorylation of T205 in the Pin1-binding motif of F-box/WD repeat-containing protein 7 (FBXW7) induces binding to the Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (PIN1) protein. Pin1 interacts with Fbw7 in a phoshorylation-dependent manner and promotes Fbw7 self-ubiquitination and protein degradation by disrupting Fbw7 dimerization. Paper also shows the over-expression of Pin1 suppresses the ability of Fbw7 to inhibit cell transformation and proliferation, suggesting a link between Pin1 overexpression and cancer.

F-box/WD repeat-containing protein 7 - FBXW7 -  Homo sapiens
TRG_NES_CRM1_21926BinaryPre‑translationalAlternative splicing removes the nuclear export signal (NES) of Isoform Archipelago beta of F-box/WD repeat-containing protein 7 (FBXW7), abrogating binding to Exportin-1 (XPO1) and export from nucleus. The presence of the NES produces an isoform with a cytoplasmic localisation. The two other isoforms of FBXW7 localise to the nucleus and the nucleolus, respectively.

G1/S-specific cyclin-E1 - CCNE1 -  Homo sapiens
DEG_SCF_FBW7_1393399SpecificityAltered binding specificityPhosphorylation of G1/S-specific cyclin-E1 (CCNE1) at S399 generates a docking site for Glycogen synthase kinase-3 beta (GSK3B). Subsequent phosphorylation of CCNE1 by Glycogen synthase kinase-3 beta (GSK3B) at T395 switches the specificity of CCNE1 to the F-box/WD repeat-containing protein 7 (FBXW7), which recruits CCNE1 to the SCF ubiquitin ligase complex to mark CCNE1 for degradation.

G1/S-specific cyclin-E1 - CCNE1 -  Homo sapiens
DEG_SCF_FBW7_1378384SpecificityAltered binding specificityPhosphorylation of Isoform E-S of G1/S-specific cyclin-E1 (CCNE1) at S384 by CDK2 primes CCNE1 for phosphorylation by Glycogen synthase kinase-3 beta (GSK3B) at T380, which creates a recognition site for F box proteins of the SCF ubiquitin ligase complex (F-box/WD repeat-containing protein 7 (FBXW7)) that target CCNE1 for degradation.

Large T antigen - -  Simian virus 40
DEG_SCF_FBW7_2699705BinaryPhysicochemical compatibilityPhosphorylation of T701 in the degron of Large T antigen induces binding to the F-box/WD repeat-containing protein 7 (FBXW7) protein, which recruits it to the SCF ubiquitin ligase complex where it is marked for degradation.

Myc proto-oncogene protein - MYC -  Homo sapiens
DEG_SCF_FBW7_15562SpecificityAltered binding specificityPhosphorylation of Myc proto-oncogene protein (MYC) at S62 by Mitogen-activated protein kinase 1 (MAPK1) primes MYC for phosphorylation by Glycogen synthase kinase-3 beta (GSK3B), which targets MYC to the SCF ubiquitin ligase complex, F-box/WD repeat-containing protein 7 (FBXW7) that marks MYC for degradation.

Neurogenic locus notch homolog protein 1 - NOTCH1 -  Homo sapiens
DEG_SCF_FBW7_225082515BinaryPhysicochemical compatibilityPhosphorylation of T2511 in the degron of Neurogenic locus notch homolog protein 1 (NOTCH1) induces binding to the F-box/WD repeat-containing protein 7 (FBXW7) protein, which recruits it to the SCF ubiquitin ligase complex where it is marked for degradation.

Sterol regulatory element-binding protein 1 - SREBF1 -  Homo sapiens
DEG_SCF_FBW7_1425430SpecificityAltered binding specificityPhosphorylation of SREBP-1 (Sterol regulatory element-binding protein 1 (SREBF1)) at S430 generates a docking site for Glycogen synthase kinase-3 beta (GSK3B). Subsequent phosphorylation of SREBP-1 (SREBF1) by GSK3B at T426 switches the specificity of SREBP-1 (SREBF1) to the F-box/WD repeat-containing protein 7 (FBXW7), which recruits SREBP-1 (SREBF1) to the SCF ubiquitin ligase complex to mark SREBP-1 (SREBF1) for degradation.

Transcription factor AP-1 - JUN -  Homo sapiens
DEG_SCF_FBW7_1236243SpecificityAltered binding specificityTranscription factor AP-1 (JUN) is primed by an unknown kinase for phosphorylation by Glycogen synthase kinase-3 beta (GSK3B), which targets JUN to the SCF ubiquitin ligase complex, F-box/WD repeat-containing protein 7 (FBXW7) that marks JUN for degradation. In v-Jun (Viral jun-transforming protein (JUN)) the residue corresponding to S243 is mutated to phenylalanine, which protects v-Jun (JUN) from degradation.
