Constitutive Androstane Receptor (CAR) is an unusual nuclear receptor. New crystal structures reveal the molecular reasons behind CAR's unique behavior and functions.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Structural Biology

Background:

  • The nuclear receptor superfamily comprises key regulators of gene expression.
  • Constitutive Androstane Receptor (CAR, NR1I3) is a member of this superfamily, known for its atypical characteristics compared to other nuclear receptors.

Purpose of the Study:

  • To elucidate the molecular basis for the unique behaviors of CAR.
  • To provide structural insights into CAR's function and regulation.

Main Methods:

  • X-ray crystallography
  • Structural analysis
  • Biochemical assays (implied)

Main Results:

  • Three novel crystal structures of CAR were determined.
