A PF10591 SPARC_Ca_bdg Secreted protein acidic and rich in cysteine Ca binding region Domain The SPARC_Ca_bdg domain of Secreted Protein Acidic and Rich in Cysteine is responsible for the anti-spreading activity of human urothelial cells. It is rich in alpha-helices. This extracellular calcium-binding domain contains two EF-hands that each coordinates one Ca2+ ion, forming a helix-loop-helix structure that not only drives the conformation of the protein but is also necessary for biological activity. The anti-spreading activity was dependent on the coordination of Ca2+ by a Glu residue at the Z position of EF-hand 2 [1]. PFAM PF10591
A PF00050 Kazal_1 Kazal-type serine protease inhibitor domain Domain Usually indicative of serine protease inhibitors. However, kazal-like domains are also seen in the extracellular part of agrins, which are not known to be protease inhibitors. Kazal domains often occur in tandem arrays. Small alpha+beta fold containing three disulphides. Alignment also includes a single domain from transporters in the OATP/PGT family Swiss:P46721. PFAM PF00050
A PF09289 FOLN Follistatin/Osteonectin-like EGF domain Domain Members of this family are predominantly found in osteonectin and follistatin and adopt an EGF-like fold [1,2]. PFAM PF09289
