Application

Rabbit polyclonal anti- HSPA1A antibody is used to tag plasma circulating 70 kDa heat shock protein for detection and quantitation by immunocytochemical and immunohistochemical (IHC) techniques. It is used as a probe to determine the presence and roles of plasma circulating 70 kDa heat shock proteins in the activation of cells containing TLR2 and TLR4 receptors, the stimulation of proinflammatory immune responses and the development of atherosclerosis.

Biochem/physiol Actions

HSPA1A is a member of the heat shock protein 70 family. In conjuction with other heat shock proteins, this protein stabilizes existing proteins against aggregation and mediates the folding of newly translated proteins in the cytosol and in organelles. It is also involved in the ubiquitin-proteasome pathway through interaction with the AU-rich element RNA-binding protein 1.

General description

Heat shock 70 kDa protein 1A (HSPA1A, eHSP70, HSP72) is an environmental stress-inducible extracellular/plasma circulating heat shock protein that interacts with effector cells of the innate immune system. HSPA1A promotes the proliferation of H22 hepatocarcinoma cells through TLR2 and TLR4 signaling. HSPAIA signaling via TLR4 may trigger O3-induced lung inflammation. HSPA1A and its in vivo antibodies may contribute to the development of atherosclerosis. HSPA1A may stimulate innate and adaptive proinflammatory immune responses.
