This domain family is found in eukaryotes, and is typically between 197 and 211 amino acids in length. This family is the C terminal region of angiomotin. Angiomotin regulates the action of angiogenesis inhibitor angiostatin [1]. The C terminal region of angiomotin appears to be involved in directing the protein chemotactically [2].
