Initiation eukaryoten
Webbedit. In molecular biology and genetics, transcriptional regulation is the means by which a cell regulates the conversion of DNA to RNA ( transcription ), thereby orchestrating gene activity. A single gene can be regulated in a range of ways, from altering the number of copies of RNA that are transcribed, to the temporal control of when the ...

WebbThe initiation of translation in eukaryotes requires a suite of eIFs that include the cap-binding complex, eIF4F. eIF4F is comprised of the subunits eIF4G and eIF4E and often the helicase, eIF4A. The eIF4G subunit serves as an assembly point for other initiation factors, whereas eIF4E binds to the 7-methyl guanosine cap of mRNA.

Webb3 nov. 2006 · At present, the exact details of the mechanism for re-initiation and internal initiation appear to vary, depending on the mRNA in question. In some instances of re-initiation, the position of the small upstream open reading frame (ORF) is important, and in some instances the amino acid sequence of the ORF is important [18, 19].
