Domain (CC)
The VWFA domain (or beta I domain) contains three cation-binding sites: the ligand-associated metal ion-binding site (LIMBS or SyMBS), the metal ion-dependent adhesion site (MIDAS), and the adjacent MIDAS site (ADMIDAS). This domain is also part of the ligand-binding site.; DOMAIN: The fibronectin type-III-like domains bind BPAG1 and plectin and probably also recruit BP230.
