Predicted to enable protein dimerization activity and ubiquitin protein ligase activity. Predicted to be involved in double-strand break repair via homologous recombination. Predicted to act upstream of or within DNA recombination. Predicted to be located in chromosome, telomeric region. Predicted to be part of Smc5-Smc6 complex. Predicted to be active in nucleus. Is expressed in head and post-vent region. Orthologous to human NSMCE1 (NSE1 homolog, SMC5-SMC6 complex component).
