Predicted to enable ATP binding activity and ATP hydrolysis activity. Predicted to be involved in double-strand break repair via homologous recombination. Predicted to be part of Smc5-Smc6 complex. Is an ortholog of C. elegans smc-5. In C. elegans, smc-5 is involved in meiotic DNA double-strand break processing involved in reciprocal meiotic recombination.
