protein_function: Involved in stress resistance and actin organization.
Hsp27 is a chaperone of the sHsp(small heat shock protein) group among ubiquitin, alpha-crystallin, Hsp20 and others. The common functions of sHsps are chaperone activity, thermotolerance, inhibition of apoptosis, regulation of cell development, and cell differentiation. They also take part in signal transduction. The HSP27 gene has 3 exons. The mouse Hsp25 gene was mapped to chromosome 5 in a region homologous to 7q in the human. They also mapped the mouse Hsp105 gene to chromosome 5 but suggested that the human homolog is probably on 13q, not chromosome 7. The standard used in this kit is recombinant human HSP27, consisting of 205 amino acids with the molecular mass of 22.7kDa.
