Identification
HMDB Protein ID CDBP01862
Secondary Accession Numbers Not Available
Name ATP-binding cassette sub-family G member 2
Description Not Available
Synonyms
  1. Breast cancer resistance protein
  2. CD338 antigen
  3. CDw338
  4. Mitoxantrone resistance-associated protein
  5. Placenta-specific ATP-binding cassette transporter
Gene Name ABCG2
Protein Type Transporter
Biological Properties
General Function Involved in ATP binding
Specific Function Xenobiotic transporter that may play an important role in the exclusion of xenobiotics from the brain. May be involved in brain-to-blood efflux. Appears to play a major role in the multidrug resistance phenotype of several cancer cell lines. When overexpressed, the transfected cells become resistant to mitoxantrone, daunorubicin and doxorubicin, display diminished intracellular accumulation of daunorubicin, and manifest an ATP- dependent increase in the efflux of rhodamine 123
