WebIn chemistry and biology a cross-link is a bond or a short sequence of bonds that links one polymer chain to another. These links may take the form of covalent bonds or ionic bonds and the polymers can be either synthetic polymers or natural polymers (such as proteins).. In polymer chemistry "cross-linking" usually refers to the use of cross-links to promote a …
WebHere, using reverse genetics, I show that Fanconi Anaemia DNA inter-strand crosslink (FA ICL) repair factors act in concert to restrict LINE-1 retrotransposition. Moreover, by purifying the recombinant FA ICL repair incision complex (SLX4-XPF-ERCC1), I show that it can cleave intermediates of retrotransposition, aborting new integrations.
