Description

Definition and Target Specificity

TGFB2 antibody binds to the TGFB2 isoform (UniProt ID: P61812), one of three TGF-β isoforms (TGFB1, TGFB2, TGFB3) with distinct roles in cellular processes . Unlike pan-TGF-β antibodies, TGFB2-specific antibodies enable isoform-selective studies, critical for dissecting context-dependent signaling in development, immunity, and disease .

Key Attributes:

  • Antigen Source: Human TGFB2 recombinant protein .

  • Clonality: Monoclonal, ensuring consistent binding specificity .

  • Applications: Validated for Western Blotting, Immunohistochemistry (IHC-P), and Immunofluorescence (IF) .

Mechanism of Action:

TGFB2 antibodies block TGFB2 binding to its receptor (TGFβ RII), inhibiting downstream Smad2/3 phosphorylation and suppressing TGF-β-mediated pathways . This inhibition disrupts processes like epithelial-mesenchymal transition (EMT), stromal activation, and immunosuppressive cell recruitment .

Target Background

Function
Transforming growth factor beta-2 proprotein is a precursor to the Latency-associated peptide (LAP) and Transforming growth factor beta-2 (TGF-beta-2) chains. LAP and TGF-beta-2 chains constitute the regulatory and active subunits of TGF-beta-2, respectively. The proprotein is essential for maintaining the TGF-beta-2 chain in a latent state during storage in the extracellular matrix. It associates non-covalently with TGF-beta-2 and regulates its activation through interaction with 'milieu molecules', such as LTBP1 and LRRC32/GARP. These milieu molecules control the activation of TGF-beta-2 and keep it in a latent state during storage in extracellular environments. Once activated following the release of LAP, TGF-beta-2 exerts its effects by binding to TGF-beta receptors (TGFBR1 and TGFBR2), which then transduce signals.
