cDNA cloning of a 20-kDa protein (p20) highly homologous to small heat shock proteins: developmental and physiological changes in rat hindlimb muscles.
A cDNA clone encoding p20, a novel member of the small heat-shock protein family in mammals, was isolated from a rat soleus cDNA library. The clone contained an insert of 1.3 kb with an open reading frame specifying a polypeptide of 162 amino-acid residues. Southern blot analysis suggested that the p20 gene is a single gene in rat genome. Developmental changes and a sciatic nerve denervation experiment suggested that the expression of p20 in rat hindlimb muscle is related to muscle contraction, and specifically in slow-twitch muscles.
