Is predicted to encode a protein with the following domains: Zinc finger, RING-type; RING-type zinc-finger; RING-type zinc-finger, LisH dimerisation motif; and Ret finger protein-like. Is an ortholog of C. elegans tam-1. In C. elegans, tam-1 is involved in chromosome segregation; negative regulation of vulval development; and transcription initiation-coupled chromatin remodeling.
