a protein of the eukaryotic initiation factor 4E family. Recognizes and binds the 7-methylguanosine-containing mRNA cap during an early step in the initiation of protein synthesis and facilitates ribosome binding by inducing the unwinding of the mRNAs secondary structures. Phosphorylation increases the ability of the protein to bind to mRNA caps and to form the EIF4F complex. Note: This description may include information from UniProtKB.
Protein type: Translation initiation; Translation
Cellular Component: mRNA cap complex; protein complex; stress granule; cytoplasm; eukaryotic translation initiation factor 4F complex
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
