WebJun 5, 2015 · When RAG1/2 and HMGB1 were first incubated with the 12RSS, a very strong preference for acquiring and cleaving a 23RSS, versus a 12RSS partner, was observed. Although the reciprocal also appeared to be true, the adherence to the 12/23 rule was more strict if the 12RSS was the first one bound ( 23 ).

WebApr 15, 2003 · V(D)J recombination is targeted by specific DNA sequences, known as recombination signal sequences (RSSs), that flank the coding segments. RSSs consist of a highly conserved heptamer (consensus 5′-CAC AGTG) and an AT-rich nonamer (consensus 5′-ACA AAAACC) separated by a spacer of either 12 or 23 base pairs (referred to as the 12 … WebRecombination signal sequences are conserved heptamer and nonamer sequences that flank the V, J, and D gene segments which undergo recombination to generate the final V region coding exon. Some of these have 12-nucleotide spacers between the heptamer and nonamer, and others have 23-nucleotide spacers.

WebV(D)J recombination requires a pair of signal sequences with spacer lengths of 12 and 23 base pairs. Cleavage by the RAG1 and RAG2 proteins was previously shown to demand only a single signal sequence.
