malfunction | enzyme LH3 downregulation decreases MMP-9 recruitment to MRC-5 and thus MMP-9/LH3 interaction | Homo sapiens |
physiological function | recruitment of matrix metalloproteinase-9 (MMP-9) to the fibroblast cell surface by lysyl hydroxylase 3 triggers transforming growth factor-beta (TGF-beta) activation and fibroblast differentiation. LH3 provides the docking mechanism for MMP-9 cell surface association via the MMP-9 FN domain. Recruitment of MMP-9 to fibroblast cell surface does not depend merely on LH3 expression at the cell membrane. LH3 provides a mechanism for deployment of MMP-9 catalytic activity at the fibroblast cell surface that promotes TGF-beta activation and the corresponding enhancement of alpha-SMA expression. MMP-9-induced TGF-beta activation promotes alpha-SMA expression in fibroblasts is consistent with a function that supports tumor progression. LH3 expressed in a variety of tumor cell types fails to recruit MMP-9 to their cell surface | Homo sapiens |
