Hsp20 is a mammalian small heat-shock protein family that occurs most abundantly in skeletal muscle and heart. It has a tendency to form dimers, via a disulphide linkage formed by an N-terminal cysteine, low heat stability and a poor chaperoning ability in comparison with other family members. Structurally, this and related proteins contain a beta-sandwich fold consisting of 8 strands in 2 beta-sheets in a greek-key topology [ 1 ].
