Slx4

Slx4
PFAM accession number:PF09494
Interpro abstract (IPR018574):

The Slx4 protein is a heteromeric structure-specific endonuclease found from fungi to mammals. Slx4 is a regulatory subunit of the SLX1-SLX4 structure-specific endonuclease that resolves DNA secondary structures generated during DNA repair and recombination [(PUBMED:19595721), (PUBMED:19596236)]. The SLX1-SLX4 complex has a preference for 5'-flap structures, and promotes symmetrical cleavage of static and migrating Holliday junctions (HJs) [(PUBMED:12832395), (PUBMED:18471978)].

Defects in SLX4 are the cause of Fanconi anemia complementation group P (FANCP), which is a disorder affecting all bone marrow elements and resulting in anemia, leukopenia and thrombopenia [(PUBMED:21240277), (PUBMED:21240275)].
