    Protocol

    Specificity / Sensitivity

    GARP/LRRC32 (E2L6B) Rabbit Monoclonal Antibody recognizes endogenous levels of total GARP/LRRC32 protein. This antibody cross-reacts with an unidentified protein of 32 kDa in some cell extracts.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala292 of human GARP/LRRC32 protein.

    Background

    Leucine-rich repeat containing 32 (LRRC32), also known as glycoprotein A repetitions predominant (GARP), is a key regulator of the TGF-beta family (TGF-β1, TGF-β2, and TGF-β3), and is primarily expressed on the surface of mesenchymal stromal cells, hepatic stellate cells, platelets, and regulatory T cells (Tregs) (1). GARP/LRRC32 enhances the suppressive function of Tregs and decreases the expression of inflammatory cytokines, IL-2, and IFNγ (2,3). GARP/LRRC32 associates via disulfide bonds with the latency-associated peptide (LAP), the regulatory chain of TGF-β, to induce integrin-dependent activation of TGF-β and secretion (1, 3-5), thereby promoting Treg function and homeostasis. As a result, targeting GARP/LRRC32 in combination with other molecules for depleting Tregs or attenuating their suppressive activity represents an opportunity for cancer immunotherapy (6,7).
