Is predicted to encode a protein with the following domains: Zinc finger, RING/FYVE/PHD-type; Zinc finger, C3HC4 type (RING finger); and Zinc finger, RING-type. Is an ortholog of C. elegans rnf-5. In C. elegans, rnf-5 is involved in several processes, including inductive cell migration; striated muscle cell development; and ubiquitin-dependent protein catabolic process.
