Rabbit Anti-Human Hsp27 Affinity Purfied pAb

0.2 mg/ml

Rabbit Anti-Human HSPB2 polyclonal antibody. Human HSPB2, mouse Hspb1 and alphabeta-crystallin are part of a diverse family of small heat shock proteins which are produced in all organisms. They function as chaperone-like proteins by binding unfolded polypeptides and preventing uncontrolled protein aggregation. HSPB2 is believed to exist mainly as oligomers of as many as 8-40 HSPB2 protein monomers in cells. Data suggests that the large oligomers of HSPB2 have a chaperone-like activity by serving as a site where unfolding proteins may bind until ATP and HSP70-dependent refolding can occur. HSPB2 is believed to protect cells by enhancing cellular glutathione levels and elevated glutathione levels have been measured in cells overexpressing HSPB2. Data from studies using wild-type HSPB2 and mutant forms in which the serine phosphorylation sites were mutated to alanines, glycines or aspartates, have shown that cellular glutathione levels depend on the oligomerization of HSPB2. Recent findings indicate that HSPB2 is also a negative regulator of cytochrome c-dependent activation of procaspase-3.
