PTMD Annotation Information


※ Protein Information

Tag Content
UniProt Accession 4EBP1_HUMAN; Q13541;
Entrez ID 1978
GenBank Protein ID
GenBank Nucleotide ID
Protein Name Eukaryotic translation initiation factor 4E-binding protein 1 (4E-BP1) (eIF4E-binding protein 1) (Phosphorylated heat- and acid-stable protein regulated by insulin 1) (PHAS-I)
Gene Name EIF4EBP1
Organism Homo sapiens
NCBI Taxa ID 9606
Functional DescriptionRepressor of translation initiation that regulates EIF4E activity by preventing its assembly into the eIF4F complex: hypophosphorylated form competes with EIF4G1/EIF4G3 and strongly binds to EIF4E, leading to repress translation. In contrast, hyperphosphorylated form dissociates from EIF4E, allowing interaction between EIF4G1/EIF4G3 and EIF4E, leading to initiation of translation. Mediates the regulation of protein translation by hormones, growth factors and other stimuli that signal through the MAP kinase and mTORC1 pathways.

※ PTM-Disease Association

NumPTMDiseaseCell TypeTypePTM SitePMID
1PhosphorylationEsophageal squamous cell carcinomaP21932407
[Reference]: As shown in Table III high p-4E-BP1 was associated with significantly higher LR but not DR. The locoregional control was excellent (97.1%) in low p-4E-BP1 tumors
2PhosphorylationOsteogenic sarcoma/OsteosarcomaP23879172
[Reference]: FIM-A treatment resulted in the inhibition of mTORC1 signaling as demonstrated by the decreased phosphorylation of p70S6K1 and 4E-BP1. Consistent with this finding, FIM-A significantly decreased the average tumor volume, nuclei staining of PCNA, and the number of intratumoral microvessels
3PhosphorylationAmeloblastomaP22977662
[Reference]: he nuclear expression of p-mTOR, p-4E-BP1 and p-p70S6K was associated with biological behaviors (invasiveness) of ABs, and p-mTOR was an independent predictor of AB
4PhosphorylationSynovial sarcomaP23861137
[Reference]: In this study, the Akt/mTOR pathway was activated and was associated with worse clinical and pathologic behavior in patients with synovial sarcoma
5PhosphorylationBreast cancer/tumor/carcinomaP17200342
[Reference]: Interestingly, p-4EBP1 was mainly expressed in poorly differentiated tumors (P < 0.001) and correlated with tumor size (P < 0.001), presence of lymph node metastasis (P = 0.002), and locoregional recurrences (P = 0.002)
6PhosphorylationHepatocellular carcinoma/Hepatocarcinoma/HepatomaU23934262
[Reference]: Both of the compounds decreased the phosphorylation levels of p70 ribosomal protein S6 kinase (S6K) and eIF4E binding protein 1 (4E-BP1), resulting in cancer cell cytotoxicity and apoptosis
7PhosphorylationLung adenocarcinomaU23934262
[Reference]: Both of the compounds decreased the phosphorylation levels of p70 ribosomal protein S6 kinase (S6K) and eIF4E binding protein 1 (4E-BP1), resulting in cancer cell cytotoxicity and apoptosis
8PhosphorylationBladder cancertumor tissueU23273076
[Reference]: In addition, patients with tumor recurrence had lower proportions of tumors with high phos-S6 (50% vs 69%, P = .04) and phos-4EBP1 (51% vs 69%, P = .05).
9PhosphorylationGastric cancerU24030871
[Reference]: Phosphorylated mTOR and phosphorylated 4E-BP1 were expressed in 71.1% and 68.4% of the human GC tissues tested, respectively; significantly higher than the levels in para-cancerous tissues (50% and 57.9%) and normal tissues (44.6% and 29%).
10PhosphorylationChronic myelogenous leukemia/Chronic myeloid leukemiatumor tissueU23384908
[Reference]: The phosphorylation of mTOR, 4E-BP1 and p70S6K were significantly increased in CML bone marrow cells compared with that of normal control (70.6% vs 30.0%, 76.5% vs 40.0%, 73.5% vs 20.0%, respectively, P < 0.05)
11Threonine PhosphorylationLiver cancercell linePT3723537100
[Reference]: CCI-779 inhibited the phosphorylation of mTOR (Ser2448), p70S6K (Thr389), S6 (Ser240/244), and 4EBP1 (Thr37/46) in different grades and the expressions of p70S6K, S6, and 4EBP1. As a result, CCI-779 induced a dose-dependent decrease in cell proliferation, G1/S arrest and damage of cell shape
12Threonine PhosphorylationOvarian cancer/carcinomaUT3721276607
[Reference]: Expression of activated mTOR in our study had no association with prognostic factors and survival of patients with ovarian cancer. In addition, the expression of p-mTOR was not correlated with that of p-4EBP1 although we used an antibody against phosphorylated 4EBP1 (Thr37/46).
13Threonine PhosphorylationNon-small cell lung cancer/carcinomacell linesUT3716397245
[Reference]: Fibronectin also increased the phosphorylation 4E-BP1 (Thr37/46), another downstream target of mTOR, in a time-dependent and dose-dependent manner with maximal induction at 24 hours
14Threonine PhosphorylationLiver cancercell linePT4623537100
[Reference]: CCI-779 inhibited the phosphorylation of mTOR (Ser2448), p70S6K (Thr389), S6 (Ser240/244), and 4EBP1 (Thr37/46) in different grades and the expressions of p70S6K, S6, and 4EBP1. As a result, CCI-779 induced a dose-dependent decrease in cell proliferation, G1/S arrest and damage of cell shape
15Threonine PhosphorylationNon-small cell lung cancer/carcinomaPT4616397245
[Reference]: We found that fibronectin stimulated the phosphorylation of Akt, an upstream inducer of mTOR, and induced the phosphorylation of p70S6K1 and eukaryotic initiation factor 4E-binding protein 1 (4E-BP1), two downstream targets of mTOR in NSCLC cells (H1792 and H1838), whereas it inhibited the phosphatase and tensin homologue deleted on chromosome 10, a tumor suppressor protein that antagonizes the phosphatidylinositol 5-kinase/Akt signal.
16Threonine PhosphorylationIntrahepatic cholangiocarcinomaPT7022248270
[Reference]: n addition, p-4EBP1 phosphorylation at Thr 70 could be a useful prognostic biomarker for ICC patients
17Threonine PhosphorylationAcute myeloid leukaemia/Acute myelogenous leukemiaPT7018056483
[Reference]: We have recently demonstrated that the mTOR/4E-BP1/p70S6K pathway is constitutively activated in AML cells but not in their normal counterpart.
18Threonine PhosphorylationRhabdomyosarcomaPT7016790088
[Reference]: We now demonstrate that CCI-779 rapidly inhibits mTOR activity, as indicated by S6 reduction and eukaryotic initiation factor 4E-binding protein 1 (4E-BP1) phosphorylation in two xenograft models of RMS within 24 hours of treatment.
