MMP13 Protein Overview: Sequence, Structure, Function and Protein Interaction

MMP13 Protein Overview

Freije et al. (1994) cloned a cDNA coding for a novel human matrix metalloproteinase (MMP) from a cDNA library derived from a breast tumor. The isolated cDNA contains an open reading frame coding for a polypeptide of 471 amino acids. The predicted protein sequence displays extensive similarity to previously known MMPs and presented all the structural features characteristic of this protein family, including the well-conserved PRCGXPD motif. In addition, it contains in its amino acid sequence several residues specific to the collagenase subfamily (tyr214, asp235, and gly237) and lacks the 9-residue insertion present in the stromelysins. Because of the structural characteristics, Freije et al. (1994) called the new MMP collagenase-3 (CLG3), since it represented the third member of this family, composed of fibroblast (MMP1; 120353) and neutrophil (MMP8; 120355) collagenases. Northern blot analysis of RNA from normal and pathologic tissues demonstrated the existence in breast tumors of 3 different mRNA species, which seemed to be the result of utilization of different polyadenylation sites present in the 3-prime noncoding region of the gene. By contrast, no CLG3 mRNA was detected either by Northern blot or RNA polymerase chain reaction analysis with RNA from other human tissues, including normal breast, mammary fibroadenomas, liver, placenta, ovary, uterus, prostate, and parotid gland. A possible role for this metalloproteinase in the tumoral process was proposed.
