By utilizing our CTLA4 antibodies, you can elevate your research and contribute to deeper insights into immune regulation.
CTLA4 (cytotoxic T-lymphocyte-associated protein 4) is a crucial immune checkpoint protein involved in regulating immune responses. It is a transmembrane protein consisting of an extracellular domain, a transmembrane domain, and an intracellular domain. The extracellular domain binds to ligands, while the intracellular domain interacts with signaling molecules to modulate T cell activation. Research on CTLA4 is pivotal for understanding immune regulation and tolerance. Blocking CTLA4 has proven effective in cancer immunotherapy by preventing its inhibitory effect and boosting the anti-tumor immune response. Additionally, a deeper understanding of CTLA4's structure and function can aid in developing innovative therapies for a range of immune-related diseases.

This gene is a member of the immunoglobulin superfamily and encodes a protein that transmits an inhibitory signal to T cells. The protein contains a V domain, a transmembrane domain, and a cytoplasmic tail. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. The membrane-bound isoform functions as a homodimer interconnected by a disulfide bond, while the soluble isoform functions as a monomer. Mutations in this gene have been associated with insulin-dependent diabetes mellitus, Graves disease, Hashimoto thyroiditis, celiac disease, systemic lupus erythematosus, thyroid-associated orbitopathy, and other autoimmune diseases.
Our company offers high-quality anti-CTLA4 recombinant antibodies, supporting research and the development of therapies targeting this important molecule.
