MeSH Heading: Werner Syndrome Helicase
Tree Number(s): D08.811.277.040.025.159.249.500; D08.811.277.352.335.375.875; D08.811.277.352.365.290.500; D08.811.399.340.249.500; D12.776.157.687.750; D12.776.660.720.750
Unique ID: D000071657
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D000071657
Scope Note: A DNA-dependent helicase and 3'-5' exonuclease. It has 3'->5' exonuclease activity towards double-stranded DNA with a 5'-overhang and binds preferentially to DNA substrates containing alternate secondary structures, such as replication forks and HOLLIDAY JUNCTIONS. Mutations in the WRN gene are associated with WERNER SYNDROME.
Entry Term(s): RECQ3 Protein; RECQL2 Protein; Werner Syndrome ATP-Dependent Helicase; Werner Syndrome RecQ-Like Helicase
Previous Indexing: Exodeoxyribonucleases (1996-2016); RecQ Helicases (2006-2016)
