Predicted to enable 3-hydroxyacyl-CoA dehydratase activity and enzyme binding activity. Predicted to be involved in several processes, including fatty acid biosynthetic process; positive regulation by virus of viral protein levels in host cell; and positive regulation of viral genome replication. Predicted to act upstream of or within I-kappaB kinase/NF-kappaB signaling; JNK cascade; and Rho protein signal transduction. Predicted to be located in endoplasmic reticulum and nuclear membrane. Predicted to be integral component of endoplasmic reticulum membrane. Orthologous to human HACD3 (3-hydroxyacyl-CoA dehydratase 3). [provided by Alliance of Genome Resources, Apr 2022]
