Dna interstrand crosslink
In genetics, crosslinking of DNA occurs when various exogenous or endogenous agents react with two nucleotides of DNA, forming a covalent linkage between them. This crosslink can occur within the same strand (intrastrand) or between opposite strands of double-stranded DNA (interstrand). These … See more Many characterized crosslinking agents have two independently reactive groups within the same molecule, each of which is able to bind with a nucleotide residue of DNA. These agents are separated based upon their source … See more Crosslinking of DNA and protein Biochemical interaction methods DNA-protein crosslinking can be caused by a variety of … See more Crosslinked DNA is repaired in cells by a combination of enzymes and other factors from the nucleotide excision repair (NER) pathway, homologous recombination, and the base excision repair (BER) pathway.

WebAug 12, 2009 · The C4'-oxidized abasic site (C4-AP) is a commonly formed DNA lesion, which generates two types of interstrand cross-links (ICLs). The kinetically favored cross-link consists of two full length strands and forms reversibly and exclusively with dA. Cross-link formation is attributed to condensation of C4-AP with the N6-amino group of dA.
