Is predicted to encode a protein with the following domains: Ring finger domain; Zinc finger, RING/FYVE/PHD-type; and Zinc finger, RING-type. Is an ortholog of C. elegans
rnf-121. In C. elegans,
rnf-121 is involved in PERK-mediated unfolded protein response; inductive cell migration; and ubiquitin-dependent ERAD pathway.
