Abstract:
The transcription factor Forkhead box L subfamily member 2 (FOXL2) is involved in craniofacial development and ovarian function. Using 2-DE and immunoblotting, we show that it is highly modified post-translationally. The most outstanding feature of its migration profile is the presence of two distinct modification "trains" and the absence of intermediates. A theoretical analysis of the modification profile of FOXL2 suggests that it undergoes parallel processive/concerted modifications. The absence of intermediates is compatible with the recruitment of poorly modified FOXL2 into a post-translational "modification factory."

Pre-mRNA Processing: Modification of pre-mRNA Ends
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a cap to the 5' end of the growing transcript. In this process, a 5' phosphate is replaced by modified guanosine that has a methyl group attached (7-methyl guanosine). This 5' cap helps the cell...
