Naa-3, or Dishevelled-binding antagonist of beta-catenin 3, is a human gene encoded by DACT3. It may also be known as: Dapper homolog 3; Antagonist of beta-catenin Dapper homolog 3; Arginine-rich region 1 protein; Dapper antagonist of catenin 3; DAPPER3; RRR1. The encoded protein has an amino acid length of 629 and a mass of 64.9 kDa. Naa-3 is a member of the Dapper family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Frog.
