    Specificity / Sensitivity

    HSPA4/Apg-2 Antibody detects endogenous levels of total HSPA4 protein.

    Species Reactivity:

    Human, Mouse, Rat, Monkey

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to human HSPA4. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    The heat shock protein HSPA4 (Apg-2, HSP70RY) is a member of the heat-shock protein 110 (Hsp 110) subfamily of Hsp70 heat-shock proteins (1). Apg-2 has chaperone ability similiar to Hsp110, and it plays a role under non-stress conditions (2). Apg-2 interacts with TJP1/ZO-1 and functions as a regulator of ZO-1-ZONAB signaling in epithelial cells in response to cellular stress (3,4).
