Description
Hsp20 is a mammalian heat shock protein that is abundant in skeletal muscle and heart. The Hsp20 family is characterized by the presence of a conserved C-terminal domain of approx. 100 residues and contains a betasandwich fold consisting of 8 strands in 2 beta-sheets in a "Greek key" conformation. Hsp20 proteins form dimers, through a disulfide linkage formed by an N-terminal cysteine
