PF09289 | Follistatin/Osteonectin-like EGF domain (FOLN) | Follistatin/Osteonectin-like EGF domain | Members of this family are predominantly found in osteonectin and follistatin and adopt an EGF-like fold [1,2]. | Domain | |
PF21333 | Follistatin, N-terminal (FST_N) | Follistatin, N-terminal | Follistatin (FST) is required for normal embryonic and ovarian follicle development. It regulates transforming growth factor-beta superfamily ligands, being described as a ligand antagonist. It consists of a N-terminal domain with a modified TB fold ... | Domain | |
PF07648 | Kazal-type serine protease inhibitor domain (Kazal_2) | Kazal-type serine protease inhibitor 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 containi ... | Domain |
