This gene encodes a protein that is an important regulator of genome stability. The protein represents the catalytic subunit of the SLX1-SLX4 structure-specific endonuclease, which can resolve DNA secondary structures that are formed during repair and recombination processes. Two identical copies of this gene are located on the p arm of chromosome 16 due to a segmental duplication; this record represents the more telomeric copy. Alternative splicing results in multiple transcript variants. Read-through transcription also occurs between this gene and the downstream SULT1A4 (sulfotransferase family, cytosolic, 1A, phenol-preferring, member 4) gene. [provided by RefSeq, Nov 2010]
GeneCards Summary for SLX1B Gene
SLX1B (SLX1 Homolog B, Structure-Specific Endonuclease Subunit) is a Protein Coding gene. Diseases associated with SLX1B include fanconi anemia, complementation group a. Among its related pathways are Resolution of D-Loop Structures and Homologous DNA Pairing and Strand Exchange. GO annotations related to this gene include crossover junction endodeoxyribonuclease activity and 5-flap endonuclease activity. An important paralog of this gene is SLX1A.
UniProtKB/Swiss-Prot for SLX1B Gene
Catalytic subunit 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.
