Flap Endonucleases MeSH Descriptor Data 2025


MeSH Heading
Flap Endonucleases
Tree Number(s)
D08.811.277.352.355.325.350
Unique ID
D045585
RDF Unique Identifier
http://id.nlm.nih.gov/mesh/D045585
Scope Note
Endonucleases that remove 5' DNA sequences from a DNA structure called a DNA flap. The DNA flap structure occurs in double-stranded DNA containing a single-stranded break where the 5' portion of the downstream strand is too long and overlaps the 3' end of the upstream strand. Flap endonucleases cleave the downstream strand of the overlap flap structure precisely after the first base-paired nucleotide, creating a ligatable nick.
Entry Term(s)
FEN-1
Fen1 Protein

Flap Endonuclease-1
RAD2 Homolog-1 Nuclease
RTH-1 Nuclease
Previous Indexing
