| Tissue Specificity | Widely expressed with highest levels in aorta, stomach, lower gastrointestinal tract, placenta, uterus, thyroid tissue and breast. Expressed in the kidney. Expressed in the lung. Up-regulated in epithelial ovarian tumors. Not expressed in normal ovaries. Also highly expressed at the tumor periphery of lung carcinoma tissue but not within the tumor. Overexpressed in breast cancers. |
| Post Translational Modifications | Gamma-carboxylation is controversial. Gamma-carboxyglutamated.gamma-carboxyglutamate residues are formed by vitamin K dependent carboxylation.this may be required for calcium binding. According to a more recent report, does not contain vitamin K-dependent gamma-carboxyglutamate residues. |
| Function | Induces cell attachment and spreading and plays a role in cell adhesion. Enhances incorporation of BMP1 in the fibronectin matrix of connective tissues, and subsequent proteolytic activation of lysyl oxidase LOX. |
