Zinc fingers

Zinc Fingers

By Jeffrey Mah

Biotechnology 2009-2010


Definition

Definition:

  • A type of small protein with 20-30 amino acids

  • Bonded to a zinc ion

  • Play essential roles

  • in DNA recognition


Found in

Found in:

  • Thousands of other proteins

  • Plants

  • Animals

  • BUT not bacteria


Function regulation

Function/Regulation:

  • The expression of genes

  • Assembly of viruses

  • Reverse transcription

  • Nucleic acid recognition

  • Stabilizes and solidifies DNA and RNA


Structure

Structure:

  • Main structure:

    • 1 tetrahedron

    • - 2 Cysteines

    • - 2 Histidines

    • - 1 zinc ion


Structure1

Structure:

The other 15-25 amino acids all face more-or-less outwards, and can be used for various functional tasks


Significance

Significance:

  • Tiny protein that helps with DNA related work

  • Researchers are currently trying to design artificial zinc fingers with different specificities
