Matrix proteins are produced as part of Gag precursor polyproteins. During viral maturation, the Gag polyprotein is cleaved into major structural proteins by the viral protease, yielding the matrix (MA), capsid (CA), nucleocapsid (NC), and some smaller peptides. Gag-derived proteins govern the entire assembly and release of the virus particles, with matrix proteins playing key roles in Gag stability, capsid assembly, transport and budding. Although matrix proteins from different retroviruses appear to perform similar functions and can have similar structural folds which predominantly consist of four closely packed alpha-helices that are interconnected through loops, their primary sequences can be very different [3]. The matrix protein, p15, is encoded by the gag gene. MA is involved in pathogenicity [1].	Domain
