ATP-abhängige DNA-Helikase Q4
Eine Helikase ist für die Überführung von doppelsträngiger in einzelsträngige DNA verantwortlich. Die vom RECQL4-Gen kodierte Helikase wird vor allem im Thymus und in den Hoden exprimiert. Mutationen sind für rezessive Erkrankungen, wie das Rothmund-Thomson-, RAPADILINO- oder Baller-Gerold-Syndrom verantwotlich.
