Predicted to enable protein dimerization activity and ubiquitin protein ligase activity. Predicted to be involved in double-strand break repair via homologous recombination; positive regulation of response to DNA damage stimulus; and postreplication repair. Predicted to act upstream of or within DNA recombination and DNA repair. Located in chromosome, centromeric region; mitotic spindle pole; and nucleus. Part of Smc5-Smc6 complex. Is expressed in pancreas epithelium. Orthologous to human NSMCE1 (NSE1 homolog, SMC5-SMC6 complex component). [provided by Alliance of Genome Resources, Apr 2022]
