Protein 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 (By similarity).

Protein tissue specificity

Widely expressed with highest levels in aorta, stomach, lower gastrointestinal tract, placenta, uterus, thyroid tissue and breast. 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.

Protein sequence and domain

Contains 1 EMI domain.; Contains 4 FAS1 domains.

Protein 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 .

Protein cellular localization

Golgi apparatus . Secreted . Secreted, extracellular space, extracellular matrix . Note: Colocalizes with BMP1 in the Golgi.
