  • Target

    • Function
      Specifically catalyzes the 21-hydroxylation of steroids. Required for the adrenal synthesis of mineralocorticoids and glucocorticoids.
    • Involvement in disease
      Adrenal hyperplasia 3
    • Sequence similarities
      Belongs to the cytochrome P450 family.
    • Domain
      The leucine-rich hydrophobic amino acid N-terminal region probably helps to anchor the protein to the microsomal membrane.
    • Cellular localization
      Endoplasmic reticulum membrane. Microsome membrane.
