MMP20

(redirected from Enamel metalloproteinase)

MMP20

A gene on chromosome 11q22.3 that encodes matrix metalloproteinase 20, which degrades amelogenin, the major protein of the enamel matrix, and two macromolecules of the cartilage extracellular matrix: aggrecan and the cartilage oligomeric matrix protein. MMP20 may play a central role in tooth enamel formation. It is also the retired HUGO symbol for what is now designated MMP25, see there.
