Mouse LRRC32/GARP Alexa Fluor® 488-conjugated Antibody

  • Species Reactivity
  • Specificity
    Detects mouse LRRC32/GARP in direct ELISAs. In direct ELISAs, approximately 50% cross-reactivity with recombinant human (rh) LRRC32 is observed and no cross-reactivity with rhLRRC3, rhLRRC4, or rhNGL-3/LRRC4B is observed.

Data Examples
Detection of LRRC32/GARP in Mouse Splenocytes by Flow Cytometry. Mouse splenocytes were stimulated with anti-CD3/anti-CD28, Mouse Recombinant IL-2 (Catalog # 402-ML), and TGF-beta for 3 days to induce regulatory T cell differentiation. Cells were stained with Rat Anti-Mouse CD4 PerCP‑conjugated Monoclonal Antibody (Catalog # FAB554C) and either (A) Rat Anti-Mouse LRRC32/GARP Alexa Fluor® 488‑conjugated Monoclonal Antibody (Catalog # FAB62291G) or (B) Rat IgG1 Alexa Fluor 488 Isotype Control (Catalog # IC005G).

Background: LRRC32/GARP
Leucine-rich Repeat Protein 32 (LRRC32), also known as GARP (Glycoprotein A Repetitions Predominant), is an 77-80 kDa type I transmembrane glycoprotein. Mature mouse LRRC32 consists of a 608 amino acid (aa) extracellular domain (ECD) that contains 22 leucine-rich repeats, followed by a 21 aa transmembrane segment, and a 14 aa cytoplasmic domain. Within the ECD, mouse LRRC32 shares 80 and 94% aa sequence identity with human and rat LRRC32, respectively. LRRC32 is expressed on hepatic stellate cells and on adult platelets. Among T cells, it is selectively expressed on activated FOXP3+ regulatory T cells (Treg). LRRC32 expression promotes the acquisition of a Treg phenotype that is characterized by reduced cellular proliferation and cytokine secretion, plus the capacity to suppress the proliferation of naïve T cells. LRRC32 binds directly to the TGF-beta latency associated peptide (LAP) and, in association with alpha V beta 8 Integrin, mediates the activation and release of TGF-beta  from the surface of activated Treg cells. The presentation of TGF-beta on Tregs contributes to their ability to suppress naïve T cell proliferation.
