Predicted to enable enzyme activator activity and enzyme binding activity. Predicted to contribute to 3'-flap endonuclease activity; 5'-flap endonuclease activity; and crossover junction endodeoxyribonuclease activity. Predicted to be involved in DNA metabolic process and regulation of telomere maintenance. Predicted to act upstream of or within response to intra-S DNA damage checkpoint signaling. Predicted to be located in cell junction; cytosol; and nucleoplasm. Predicted to be part of Slx1-Slx4 complex. Predicted to colocalize with chromatin and chromosome, telomeric region. Human ortholog(s) of this gene implicated in Fanconi anemia complementation group P. Orthologous to human SLX4 (SLX4 structure-specific endonuclease subunit).
