FEN1 Knockout cell line (A549) Order

Catalog#：YKO-H789

Price (USD)：-

Size： 1*10^6

Instruction：

Exclusive Red Cotton system（en.rc-crispr.com）was used to design the sgRNA fragment knockout strategy. Two sgRNAs were constructed into CRISPR-U™ plasmid which will be subsequentially transfected into cells by electroporation/virus method. And the single-cell clones were isolated by the limited dilution method and the Monoclone Genotype Validation Kit (Cat: YK-MV-1000) was used for cell lysis and PCR amplification on the single-cell clones, and then the genotype was verified by Sanger sequencing. Upon passing the final validation, the positive clones were expanded and cryopreserved.

Official full symbol

flap structure-specific endonuclease 1

Also known as

FEN-1, MF1, RAD2

The protein encoded by this gene removes 5' overhanging flaps in DNA repair and processes the 5' ends of Okazaki fragments in lagging strand DNA synthesis. Direct physical interaction between this protein and AP endonuclease 1 during long-patch base excision repair provides coordinated loading of the proteins onto the substrate, thus passing the substrate from one enzyme to another. The protein is a member of the XPG/RAD2 endonuclease family and is one of ten proteins essential for cell-free DNA replication. DNA secondary structure can inhibit flap processing at certain trinucleotide repeats in a length-dependent manner by concealing the 5' end of the flap that is necessary for both binding and cleavage by the protein encoded by this gene. Therefore, secondary structure can deter the protective function of this protein, leading to site-specific trinucleotide expansions.
