Gene Information

human ... CBS(875)

General description

CBS (cystathionine-β-synthase) contains amino-terminal heme binding, central catalytic, and carboxyl-terminal regulatory domains.

Immunogen

Cystathionine beta-synthase recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

CBS (cystathionine-β-synthase) encodes a heme containing protein that catalyzes the conversion of serine and homocysteine to cystathionine, which is the first step in the transsulfuration pathway. It acts as a homotetramer and uses pyridoxal phosphate as a cofactor. S-adenosylmethionine (SAM) binding to CBS activates catalytic domain of CBS. Defects in this gene lead to deficiency of CBS causing homocystinuria, which is characterized by increased levels of the toxic metabolite homocysteine. Higher levels of homocysteine are associated with increased risk for cardiovascular diseases, Alzheimer′s disease and with neural tube defects. Polymorphism in it is also linked to bipolar disorder. Presence of CBS in human fallopian tube epithelium is crucial for production of gaseotransmitter, hydrogen sulphide, which relaxes the spontaneous contraction of the human oviduct. It is up-regulated in colon cancer cells and supports tumor growth and stimulates angiogenesis and vasorelaxation.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

Increased levels of homocysteine have been observed in various psychiatric disorders, among them in schizophrenia, depression and bipolar mood disorder. Of the genes connected with homocysteine metabolism, some studies have found an association between polymorphism of the methylenetetrahydrofolate reductase (MTHFR)

Cystathionine β-synthase (CBS) is a key enzyme in sulfur metabolism, and its inherited deficiency causes homocystinuria. Mammalian CBS is modulated by the binding of S-adenosyl-l-methionine (AdoMet) to its regulatory domain, which activates its catalytic domain. To investigate the underlying mechanism

Embryo retention in the fallopian tube is thought to lead to ectopic pregnancy, which is a significant cause of morbidity. Hydrogen sulphide (H2S) is a gaseotransmitter produced mainly by cystathionine-γ-lyase and cystathionine-β-synthase. Here we show that cystathionine-γ-lyase and cystathionine -β-synthase

Cystathionine beta-synthase (CBS) is a unique heme- containing enzyme that catalyzes a pyridoxal 5'-phosphate (PLP)-dependent condensation of serine and homocysteine to give cystathionine. Deficiency of CBS leads to homocystinuria, an inherited disease of sulfur metabolism characterized by increased levels of

Recent data show that colon cancer cells selectively overexpress cystathionine-β-synthase (CBS), which produces hydrogen sulfide (H2S), to maintain cellular bioenergetics, support tumor growth and stimulate angiogenesis and vasorelaxation in the tumor microenvironment.
