Immunocytochemistry/ Immunofluorescence - Anti-FEN1 antibody [4D9] (AB314001)

Immunofluorescence staining of HeLa (Human epithelial cell line from cervix adenocarcinoma) cells with ab314001 at 1 : 25, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor® 488-conjugated Goat Anti-Rabbit IgG (H+L).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-FEN1 antibody [4D9] (AB314001)

Immunohistochemical analysis of ab314001 diluted at 1 : 77.5 and staining in paraffin-embedded human small intestine tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

Supplementary information

Flap Endonuclease 1 known as FEN1 or FEN-1 is an important protein involved in DNA replication and repair. This protein shows a molecular weight of approximately 42 kDa. FEN1 functions as an endonuclease where it removes 5’ overhanging flaps in DNA products that occur during DNA replication and repair processes. It expresses in a wide range of human tissues with significant presence in the nucleus where DNA synthesis mainly occurs.
Biological function summary

FEN1 plays an important role in the Okazaki fragment maturation during lagging strand synthesis and long-patch base excision repair. FEN1 is not a solitary actor; it forms a part of larger complexes essential for maintaining genomic stability. It works closely with proliferating cell nuclear antigen (PCNA) to enhance its function and to interact with other proteins essential for the stability of the DNA.

Pathways

DNA replication and repair processes heavily rely on the activity of FEN1. It’s a component of the DNA replication fork protection and repair pathway and interacts with other proteins such as DNA polymerase and DNA ligase I to complete the repair process. Efficient DNA replication ensures accurate genomic duplication preventing mutations that could lead to severe cellular malfunction.

FEN1 is linked to the development of cancer and neurodegenerative diseases like Huntington's disease. FEN1 mutations or malfunction can result in genomic instability and an increased risk of tumorigenesis. In the context of neurodegenerative diseases deficiencies in FEN1 activity may disrupt the repair of oxidative DNA damage which is an important feature of disorders like Huntington's. These insights highlight the need for further research into FEN1's role and interactions to develop potential therapeutic strategies.

Target data

Structure-specific nuclease with 5'-flap endonuclease and 5'-3' exonuclease activities involved in DNA replication and repair. During DNA replication, cleaves the 5'-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. It enters the flap from the 5'-end and then tracks to cleave the flap base, leaving a nick for ligation. Also involved in the long patch base excision repair (LP-BER) pathway, by cleaving within the apurinic/apyrimidinic (AP) site-terminated flap. Acts as a genome stabilization factor that prevents flaps from equilibrating into structures that lead to duplications and deletions. Also possesses 5'-3' exonuclease activity on nicked or gapped double-stranded DNA, and exhibits RNase H activity. Also involved in replication and repair of rDNA and in repairing mitochondrial DNA.
