Immunoprecipitation - Anti-Indoleamine 2, 3-dioxygenase antibody [BLR040F] - BSA free (AB272090)

Indoleamine 2,3-Dioxygenase was immunoprecipitated from 1.0 mg HeLa whole cell lysate with ab243896 at 15 μl per reaction. Western blot was performed on the immunoprecipitate using ab243896 at 1/1000 dilution.

Lane 1 : ab243896 IP in HeLa whole cell lysate.

Lane 2 : Control IgG in HeLa whole cell lysate.

Detection : Chemiluminescence with an exposure time of 30 seconds.

This data was developed using the same antibody clone in a different buffer formulation containing Borate buffered saline, BSA, glycerol and sodium azide (ab243896).

Indoleamine 2 3-dioxygenase (IDO) also known as IDO1 is an enzyme involved in the catabolism of tryptophan to kynurenine. It weighs approximately 45 kDa and it is an important target in immunoregulatory processes. IDO is highly expressed in antigen-presenting cells such as dendritic cells and macrophages as well as in various tumor cells where it helps modulate immune responses. This enzyme can also be measured by using assays like IDO ELISA.

Biological function summary

IDO plays a role in immune response regulation by degrading tryptophan an essential amino acid needed for T-cell proliferation. The depletion of tryptophan and the accumulation of its metabolites such as kynurenine cause immunosuppressive effects within the tissue microenvironment. While IDO functions mostly as a standalone enzyme its activity influences the cellular surroundings by altering the balance of local immune reactions.

Pathways

IDO integrates into the tryptophan metabolism pathway and is important in the kynurenine pathway. Through this pathway it maintains immune homeostasis and cell defense mechanisms. Proteins like kynureninase and kynurenine 3-monooxygenase also participate in the same metabolic processes which further extend the effects of tryptophan metabolism on immune cell behavior.

IDO is linked with cancer and chronic inflammatory conditions. In cancer elevated IDO expression suppresses anti-tumor immunity aiding tumor cells to evade immune surveillance. It also plays a role in autoimmune disorders by regulating excessive immune activity. During cancer progression IDO often works in conjunction with immune checkpoint proteins like PD-L1 which further enhances its immunosuppressive capabilities within the tumor microenvironment.

Target data

Catalyzes the first and rate limiting step of the catabolism of the essential amino acid tryptophan along the kynurenine pathway (PubMed : 17671174, PubMed : 18026683). Involved in the peripheral immune tolerance, contributing to maintain homeostasis by preventing autoimmunity or immunopathology that would result from uncontrolled and overreacting immune responses (PubMed : 25691885). Tryptophan shortage inhibits T lymphocytes division and accumulation of tryptophan catabolites induces T-cell apoptosis and differentiation of regulatory T-cells (PubMed : 25691885). Acts as a suppressor of anti-tumor immunity (PubMed : 14502282, PubMed : 23103127, PubMed : 25157255, PubMed : 25691885). Limits the growth of intracellular pathogens by depriving tryptophan (PubMed : 25691885). Protects the fetus from maternal immune rejection (PubMed : 25691885).
