malfunction | Cartoon mice harbor the single point mutation S466P in the MT1-MMP hemopexin domain, a 200-amino acid segment. The S466P substitution generates a misfolded, temperature-sensitive mutant that is abnormally retained in the endoplasmic reticulum (ER). The MT1-MMPS466P mutation replicates the phenotypic status of Mt1-mmp-null animals as well as the functional characteristics of MT1-MMP-/- cells. The wild-type hemopexin domain does not play a required role in regulating MT1-MMP trafficking, as a hemopexin domain-deletion mutant is successfully mobilized to the cell surface and displays nearly normal collagenolytic activity. Cartoon mice exhibit a pattern of stunted growth, kyphosis, and rounded skulls, Cartoon mouse phenotype, detailed overview. Cartoon mouse fibroblasts are devoid of pericellular collagenolytic activity | Mus musculus |
