Rabbit anti-Human EIF4ENIF1 Polyclonal Antibody

Uniprot Id

Q9NRA8

Target Species

Human

Target Name

EIF4ENIF1

Target Full Name

Eukaryotic translation initiation factor 4E transporter

Target Function

EIF4E-binding protein that regulates translation and stability of mRNAs in processing bodies (P-bodies). Plays a key role in P-bodies to coordinate the storage of translationally inactive mRNAs in the cytoplasm and prevent their degradation. Acts as a binding platform for multiple RNA-binding proteins: promotes deadenylation of mRNAs via its interaction with the CCR4-NOT complex, and blocks decapping via interaction with eIF4E (EIF4E and EIF4E2), thereby protecting deadenylated and repressed mRNAs from degradation. Component of a multiprotein complex that sequesters and represses translation of proneurogenic factors during neurogenesis. Promotes miRNA-mediated translational repression. Required for the formation of P-bodies. Involved in mRNA translational repression mediated by the miRNA effector TNRC6B by protecting TNRC6B-targeted mRNAs from decapping and subsequent decay. Also acts as a nucleoplasmic shuttling protein, which mediates the nuclear import of EIF4E and DDX6 by a piggy-back mechanism.

Target Background

The protein encoded by this gene is a nucleocytoplasmic shuttle protein for the translation initiation factor eIF4E. This shuttle protein interacts with the importin alpha-beta complex to mediate nuclear import of eIF4E. It is predominantly cytoplasmic; its own nuclear import is regulated by a nuclear localization signal and nuclear export signals. Multiple transcript variants encoding different isoforms have been found for this gene.
