Transforming Growth Factor Beta Receptor I Human Recombinant
Produced in Sf9 insect cells using a baculovirus expression system, this recombinant TGFBR1 protein is a single, glycosylated polypeptide chain consisting of 342 amino acids (27-126a.a.). It has a molecular weight of 38.0 kDa, although it may appear between 40-57 kDa on SDS-PAGE due to glycosylation. This protein is expressed with a 242 amino acid hIgG-His tag at the C-terminus and purified using proprietary chromatographic techniques.

Transforming Growth Factor Beta Receptors (TGFBR) are a group of transmembrane serine/threonine kinase receptors that play a crucial role in the TGF-β signaling pathway. These receptors are classified into three main types: TGFBR1, TGFBR2, and TGFBR3. TGFBR1 and TGFBR2 are primarily involved in signal transduction, while TGFBR3, also known as betaglycan, acts as a co-receptor that enhances the binding of TGF-β ligands to TGFBR2 .
Key Biological Properties: TGFBRs are involved in various cellular processes, including cell growth, differentiation, apoptosis, and immune responses. They are ubiquitously expressed in almost all cell types and tissues .
Expression Patterns and Tissue Distribution: TGFBR1 and TGFBR2 are widely expressed in many tissues, including the lungs, liver, kidneys, and immune cells. TGFBR3 is predominantly found in the heart, lungs, and kidneys .
Primary Biological Functions: TGFBRs are essential for regulating cell proliferation, differentiation, and apoptosis. They play a significant role in maintaining tissue homeostasis and immune responses .
Role in Immune Responses and Pathogen Recognition: TGFBRs are involved in modulating immune responses by regulating the activity of various immune cells, including T-cells and macrophages. They help in pathogen recognition and the subsequent immune response .
Mechanisms with Other Molecules and Cells: TGFBRs interact with TGF-β ligands, leading to the formation of receptor complexes. TGFBR2 phosphorylates and activates TGFBR1, which then propagates the signal downstream .
Binding Partners and Downstream Signaling Cascades: Upon activation, TGFBR1 phosphorylates receptor-regulated SMAD proteins (R-SMADs), which then form complexes with co-SMADs and translocate to the nucleus to regulate gene expression .
Regulatory Mechanisms Controlling Expression and Activity: The expression and activity of TGFBRs are tightly regulated at multiple levels, including transcriptional regulation and post-translational modifications such as phosphorylation and ubiquitination .
Transcriptional Regulation and Post-Translational Modifications: TGFBR signaling is modulated by various feedback loops and regulatory proteins that ensure the robustness, duration, and specificity of the signaling pathway .
Biomedical Research: TGFBRs are extensively studied in the context of cancer, fibrosis, and cardiovascular diseases. They are potential targets for therapeutic interventions .
Diagnostic Tools and Therapeutic Strategies: Antibodies targeting TGFBRs are used in diagnostic assays such as Western Blot, Immunohistochemistry, and ELISA. Therapeutic strategies include the development of small-molecule inhibitors and monoclonal antibodies .
Role Throughout the Life Cycle: TGFBRs play a critical role in various stages of the life cycle, from embryonic development to aging. They are involved in tissue homeostasis, wound healing, and the regulation of immune responses .
From Development to Aging and Disease: Dysregulation of TGFBR signaling is associated with various diseases, including cancer, fibrosis, and autoimmune disorders. Understanding the role of TGFBRs in these processes is crucial for developing effective therapeutic strategies .
