Summary

SLX4 (SLX4 structure-specific endonuclease subunit, HGNC:23845) is a protein-coding gene on chromosome 16p13.3, encoding Structure-specific endonuclease subunit SLX4 (Q8IY92). Regulatory subunit that interacts with and increases the activity of different structure-specific endonucleases. It is a selective cancer dependency (DepMap: 11.5% of cell lines).

This gene encodes a protein that functions as an assembly component of multiple structure-specific endonucleases. These endonuclease complexes are required for repair of specific types of DNA lesions and critical for cellular responses to replication fork failure. Mutations in this gene were found in patients with Fanconi anemia.

Function. Regulatory subunit that interacts with and increases the activity of different structure-specific endonucleases. Has several distinct roles in protecting genome stability by resolving diverse forms of deleterious DNA structures originating from replication and recombination intermediates and from DNA damage. Component of the SLX1-SLX4 structure-specific endonuclease that resolves DNA secondary structures generated during DNA repair and recombination. Has endonuclease activity towards branched DNA substrates, introducing single-strand cuts in duplex DNA close to junctions with ss-DNA. Has a preference for 5’-flap structures, and promotes symmetrical cleavage of static and migrating Holliday junctions (HJs). Resolves HJs by generating two pairs of ligatable, nicked duplex products. Interacts with the structure-specific ERCC4-ERCC1 endonuclease and promotes the cleavage of bubble structures. Interacts with the structure-specific MUS81-EME1 endonuclease and promotes the cleavage of 3’-flap and replication fork-like structures. SLX4 is required for recovery from alkylation-induced DNA damage and is involved in the resolution of DNA double-strand breaks.

Subunit / interactions. Forms a heterodimer with SLX1A/GIYD1. Interacts with ERCC4/XPF; catalytic subunit of the ERCC4-ERCC1 endonuclease. Interacts with MUS81; catalytic subunit of the MUS81-EME1 endonuclease. Interacts with MSH2; component of the MSH2-MSH3 mismatch repair complex. Interacts with TERF2-TERF2IP. Interacts with PLK1 and SLX4IP.

Subcellular location. Nucleus.

Disease relevance. Fanconi anemia complementation group P (FANCP) [MIM:613951] A disorder affecting all bone marrow elements and resulting in anemia, leukopenia and thrombopenia. It is associated with cardiac, renal and limb malformations, dermal pigmentary changes, and a predisposition to the development of malignancies. At the cellular level it is associated with hypersensitivity to DNA-damaging agents, chromosomal instability (increased chromosome breakage) and defective DNA repair. Some individuals affected by Fanconi anemia of complementation group P have skeletal anomalies. The disease is caused by variants affecting the gene represented in this entry.

Similarity. Belongs to the SLX4 family.

Enriched among interaction partners

Reactome pathways and GO biological processes over-represented among this gene’s 73 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
