一般描述
The gene E1F4EBP1 (eukaryotic translation initiation factor 4E binding protein 1) is mapped to human chromosome 8p11-p12. It belongs to the translation repressor protein family.
Human E1F4EBP1 (eukaryotic translation initiation factor 4E binding protein 1)(GenBank Accession No. NM_004095), full length with N-terminal His tag, MW = 13.6kDa, expressed inEscherichia coli.
应用
4EBP1 Active human has been used as a substrate forin vitrokinase assay.
生化/生理作用
E1F4EBP1 (eukaryotic translation initiation factor 4E binding protein 1) is involved in protein synthesis, cell growth and survival. In unphosphorylated form, it suppresses the translation initiation of capped mRNAs. On the other hand, in phosphorylated form, it increases translation initiation. Phosphorylation of E1F4EBP1 releases it from eIF4E (eukaryotic translation initiation factor 4E), thereby resulting in cap-dependent translation. E1F4EBP1 is also involved in tumorigenesis and the gene is overexpressed in various carcinomas. It is also a substrate for mTORC1 (mammalian target of rapamycin complex 1). In non-phosphorylated conditions, it interacts with p21 (cyclin-dependent kinase inhibitor) and enhances destabilization of p21.
