                                                       Zinc Finger Motif

Zinc atom stabilizes the structure/fold by coordination bonds

Each motif contains about 30-50 amino acids

Contains regular patterns of Cys / His, which coordinate with Zinc atom

Contains one helix and two small anti-parallel beta sheets in each finger

Zinc holds helix and beta-sheets together

Helix binds to DNA

CFTR protein contains

a di-acidic sorting signal that binds to the Sec24 subunit

of the COPII vesicle coat and is necessary for transport of

the CFTR protein out of the ER.
