Cystatin-like domain; Cystatins are a family of cysteine protease inhibitors that occur mainly as single domain proteins. However some extracellular proteins such as kininogen, His-rich glycoprotein and fetuin also contain these domains.

Cystatin domain; Very diverse family. Attempts to define separate sub-families failed. Typically, either the N-terminal or C-terminal end is very divergent. But splitting into two domains would make very short families. pfam00666 is related to this family but has not been included.

 37-84 2.38e-04

Aspartic acid proteinase inhibitor; SQAPI, aspartic acid inhibitor first isolated from squash, inhibits a wide range of aspartic proteinases. This particular family of PAAPIs (proteinaceous aspartic acid inhibitors) seems to have evolved quite recently from an ancestral cystatin. Structurally it consists of a four-stranded anti-parallel beta-sheet gripping an alpha-helix in much the same manner that a hand grips a tennis racket. The unstructured N-terminus and the loop connecting beta-strands 1 and 2 are important for pepsin inhibition, but the loop connecting strands 3 and 4 is not.
