Conserved 12-bp element downstream from mRNA polyadenylation sites
1National Accelerator Centre, Council for Scientific and Industrial Research, Faure, South Africa.
Abstract:
Sequences downstream from the AATAAA motif in a number of cellular and viral transcription units have been compared. A 12-bp conserved element was identified in approximately half of the cases studied, and a consensus sequence TTGANNNTTTTTT was derived from a comparison of 74 such sequences. This element is located immediately (5-20 bp) downstream from the poly(A)-addition site in every case where this is known, and it is suggested that this element may be involved in the cleavage/polyadenylation reaction. This proposal is consistent with published studies on deletion mutants of downstream regions.

pre-mRNA Processing
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 to it (7-Methyl guanosine). This 5’ cap helps the...
