Homology between CT46/HORMAD1, KOG4652, and MGC26710. Amino acid sequence alignment between CT46/HORMAD1 and the prototype HORMA domain-containing protein KOG4652 (top), and between CT46/HORMAD1 and the homologous MGC26710 hypothetical protein (bottom). Identical sequences are indicated by the amino acid residue, conservative amino acid changes by plus signs, and gaps by dashes.
