Multigene families are defined as groups of genes with sequence homology and related overlapping functions, whereas superfamilies are defined as a group of proteins or genes of common origin with nonoverlapping functions. If a group of proteins or genes contains a domain of common origin, it is a superfamily; a protein or a gene may belong to two or more superfamilies.
