Predicted to enable ubiquitin ligase-substrate adaptor activity. Involved in blastocyst formation. Acts upstream of or within regulation of ERK1 and ERK2 cascade and stem cell population maintenance. Predicted to be part of Cul2-RING ubiquitin ligase complex. Predicted to be active in cytoplasm. Is expressed in 2-cell stage embryo; 4-cell stage embryo; compacted morula; and inner cell mass. Orthologous to several human genes including PRAMEF1 (PRAME family member 1); PRAMEF10 (PRAME family member 10); and PRAMEF11 (PRAME family member 11).
