Western blot - Anti-CBS antibody [EPR8578] - BSA and Azide free (AB248359)

This data was developed using the same antibody clone in a different buffer formulation (ab131155).

Lanes 1-3 : Merged signal (red and green). Green - ab131155 observed at 70 kDa. Red - loading control, ab8245 observed at 37 kDa.

ab131155 Anti-CBS antibody [EPR8578] was shown to specifically react with CBS in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab264950 (knockout cell lysate ab257203) was used. Wild-type and CBS knockout samples were subjected to SDS-PAGE. ab131155 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 10000 dilution for 1 hour at room temperature before imaging.

Supplementary information

Cystathionine beta-synthase (CBS) is an enzyme that catalyzes the conversion of homocysteine and serine into cystathionine. It is sometimes referred to as CBS monelyne or cystathionine synthase. CBS is a heme-containing protein with a molecular mass of approximately 63 kDa. It is expressed widely in tissues including the liver brain and kidney. The activity of CBS is regulated by various factors including the availability of cofactors like pyridoxal 5'-phosphate and adenosine triphosphate (ATP).

Biological function summary

The enzyme CBS plays a role in the transsulfuration pathway where it helps in the metabolism of homocysteine. CBS is a part of a larger complex in some tissues where it interacts with other enzymes involved in sulfur amino acid metabolism. This function is important in maintaining cellular sulfur amino acid balance and protecting cells from oxidative stress caused by elevated levels of homocysteine.

Pathways

CBS functions in the transsulfuration pathway which connects the methionine cycle and the synthesis of glutathione. This pathway is essential for detoxification and antioxidant protection. CBS interrelates with other proteins like cystathionine gamma-lyase (CGL) within this pathway. The interplay between CBS and CGL ensures the conversion of homocysteine to cysteine which is a precursor for the synthesis of glutathione.

CBS deficiency is linked to homocystinuria a disorder characterized by high levels of homocysteine in the blood and urine. Symptoms include cardiovascular problems and developmental delays. Furthermore alterations in CBS activity relate to cardiovascular diseases due to hyperhomocysteinemia. Within these conditions CBS interacts with other proteins involved in homocysteine metabolism such as methionine synthase which also contributes to the complexity of these disorders.

Target data

Hydro-lyase catalyzing the first step of the transsulfuration pathway, where the hydroxyl group of L-serine is displaced by L-homocysteine in a beta-replacement reaction to form L-cystathionine, the precursor of L-cysteine. This catabolic route allows the elimination of L-methionine and the toxic metabolite L-homocysteine (PubMed : 20506325, PubMed : 23974653, PubMed : 23981774). Also involved in the production of hydrogen sulfide, a gasotransmitter with signaling and cytoprotective effects on neurons (By similarity).
