Plays a role in cell adhesion (PubMed:8024701). May play a role in cell-collagen interactions (By similarity). Binds to type I, II, and IV collagens. May be associated both with microfibrils and with the cell surface (PubMed:8077289). Highly expressed in the corneal epithelium (PubMed:27609313, PubMed:8077289). Expressed in heart, placenta, lung, liver, skeletal muscle, kidney and pancreas (PubMed:8077289). By TGF-beta (PubMed:1388724, PubMed:8024701). Gamma-carboxylation is controversial. Gamma-carboxyglutamated; gamma-carboxyglutamate residues are formed by vitamin K dependent carboxylation; these residues may be required for binding to calcium (PubMed:18450759). According to a more recent report, does not contain vitamin K-dependent gamma-carboxyglutamate residues (PubMed:26273833). The EMI domain contains 2 expected intradomain disulfide bridges (Cys-49-Cys85 and Cys-84-Cys-97) and one unusual interdomain disulfide bridge to the second FAS1 domain (Cys-74-Cys-339). This arrangement violates the predicted disulfide bridge pattern of an EMI domain. The disease is caused by variants affecting the gene represented in this entry.
