SYNONYMS

4E-BP1 antibody; 4EBP1 antibody; 4EBP1_HUMAN antibody; BP 1 antibody; eIF4E binding protein 1 antibody; eIF4E-binding protein 1 antibody; Eif4ebp1 antibody; Eukaryotic translation initiation factor 4E-binding protein 1 antibody; PHAS-I antibody; PHASI antibody; Phosphorylated heat- and acid-stable protein regulated by insulin 1 antibody

SEQUENCE SIMILARITIES

Belongs to the eIF4E-binding protein family.

POST-TRANSLATIONAL MODIFICATION

Phosphorylated on serine and threonine residues in response to insulin, EGF and PDGF. Phosphorylation at Thr-37, Thr-46, Ser-65 and Thr-70, corresponding to the hyperphosphorylated form, is regulated by mTORC1 and abolishes binding to EIF4E.; Ubiquitinated: when eIF4E levels are low, hypophosphorylated form is ubiquitinated by the BCR(KLHL25) complex, leading to its degradation and serving as a homeostatic mechanism to maintain translation and prevent eIF4E inhibition when eIF4E levels are low. Not ubiquitinated when hyperphosphorylated (at Thr-37, Thr-46, Ser-65 and Thr-70) or associated with eIF4E.

SUBCELLULAR LOCATION

Cytoplasm. Nucleus.

FUNCTION

The translation of proteins from eukaryotic mRNA is initiated by the multisubunit complex eIF-4F, which associates with the mRNA 5' cap structure. eIF-4E, a component of eIF-4F, is responsible for binding to the 5' cap structure and for the assembly of the eIF-4F complex. The regulatory protein 4E-BP1, also referred to as PHAS-I, inhibits eIF-4E function. Phosphorylation of 4E-BP1 by S6 kinase p70, MAP kinases or PKCs causes the disassociation of 4E-BP1 from eIF-4E, promoting translation. A protein that is functionally related to 4E-BP1, designated 4E-BP2, also associates with eIF-4E.
