Enables miRNA binding activity and ubiquitin protein ligase activity. Involved in several processes, including miRNA metabolic process; protein autoubiquitination; and regulation of gene expression. Acts upstream of or within several processes, including neural tube closure; positive regulation of gene silencing by miRNA; and regulation of protein metabolic process. Located in P-body. Is expressed in several structures, including dorsal root ganglion; ileum; limb bud; male reproductive gland or organ; and tail. Orthologous to human TRIM71 (tripartite motif containing 71).
