The HORMA (for Hop1p, Rev7p and MAD2) domain has been suggested to recognise chromatin states that result from DNA adducts, double stranded breaks or non-attachment to the spindle and acts as an adaptor that recruits other proteins. MAD2 is a spindle checkpoint protein which prevents progression of the cell cycle upon detection of a defect in mitotic spindle integrity.	Domain
