Description : This gene is a member of the immunoglobulin superfamily and encodes a protein which 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.
Source : HEK293
Species : Human
Tag : His
Form : Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Trehalose are added as protectants before lyophilization.
Molecular Mass : Biotinylated CTLA4 /CD152, fused with 6×His tag at the C-terminus, has a calculated MW of 14.3 kDa. The predicted N-terminus is Ala 37 . DTT-reduced Protein migrates as 25 kDa due to glycosylation.
Endotoxin : Less than 1.0 EU per μg of the Biotinylated CTLA4 /CD152 by the LAL method.

Q&As (5)

Ask a question
Are there ongoing clinical trials exploring CTLA-4 inhibitors in combination with other immunotherapies? 05/16/2020

Yes, several clinical trials are investigating the combination of CTLA-4 inhibitors with PD-1 inhibitors and other immunotherapies to improve the overall effectiveness of cancer treatment.

How does the expression of CTLA-4 vary in different types of immune cells? 10/17/2019

CTLA-4 is expressed on various immune cells, including T cells, regulatory T cells (Tregs), and some B cells, contributing to its diverse immunoregulatory functions.

In what ways can CTLA-4 be utilized in organ transplantation? 01/11/2017

Modulating CTLA-4 may have applications in organ transplantation by suppressing the immune response against transplanted tissues and reducing the risk of rejection.

How does CTLA-4 contribute to the maintenance of immune tolerance? 04/30/2016

CTLA-4 is involved in the suppression of autoreactive T cells, contributing to the prevention of autoimmune responses by maintaining immune tolerance.

How does CTLA-4 blockade differ from PD-1/PD-L1 blockade in cancer immunotherapy? 03/18/2016

While both CTLA-4 and PD-1/PD-L1 inhibitors enhance anti-tumor immune responses, they target different checkpoints in the immune system. CTLA-4 primarily regulates T-cell activation in the early stages, whereas PD-1/PD-L1 acts later in the immune response.
