MMP21(redirected from matrix metalloproteinase 21)
MMP21A gene on chromosome 10q26.13 that encodes matrix metalloproteinase 21, which cleaves alpha-1-antitrypsin and may have a role in embryogenesis and tumour progression. MMP21 is also a less preferred gene symbol for what is now designated as MMP23A (see there), and a less preferred gene symbol for what is now designated as MMP23B (see there).
