DNA Flanking Region. The term 'flanking region' usually refers to regions of the genome up to 103-104 bases on either side of the terminal exons of a gene, and which especially contain promoter and other regulatory sequences [99,100]. From: Cancer Letters, 2004. View all Topics.CRISPR/Cas13a (formerly C2c2) from the bacterium Leptotrichia shahii is an RNA-guided CRISPR system that targets sequences in RNA rather than DNA. PAM is not relevant for an RNA-targeting CRISPR, although a guanine flanking the target negatively affects efficacy, and has been designated a "protospacer flanking site" (PFS). GUIDE-SeqBy analyzing the effects of single base substitutions around the ATG initiator codon in a cloned preproinsulin gene, I have identified ACCATGG as the optimal sequence for initiation by eukaryotic ribosomes. Mutations within that sequence modulate the yield of proinsulin over a 20-fold range. A purine in position -3 (i.e., 3 nucleotides upstream from the ATG codon) has a …What is a 3 flanking region?
