PRAMEF18

Summary

PRAMEF18 (PRAME family member 18, HGNC:30693) is a protein-coding gene on chromosome 1p36.21, encoding PRAME family member 18 (Q5VWM3). It is a selective cancer dependency (DepMap: 13.6% of cell lines).

Predicted to enable ubiquitin-like ligase-substrate adaptor activity. Predicted to be involved in proteasome-mediated ubiquitin-dependent protein catabolic process. Predicted to be part of Cul2-RING ubiquitin ligase complex. Predicted to be active in cytoplasm.
