Gene Information

human ... CHKB(1120)

General description

The gene CHKB (Choline/ethanolamine kinase β) is mapped to human chromosome 22q13.33. It belongs to choline kinase family of proteins.


Choline/ethanolamine kinase recombinant protein epitope signature tag (PrEST)

Biochem/physiol Actions

Choline/ethanolamine kinase β (CHKB) is crucial for phospholipid biosynthesis. It is involved in synthesis of phosphocholine and phosphoethanolamine using choline and ethanolamine as substrates, respectively. Mutations in CHKB are associated with megaconial congenital muscular dystrophy due to decrease in levels of phosphatidylcholine.

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.


Corresponding Antigen APREST74582.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
