RECQL5 helicase: Connections to DNA recombination and RNA polymerase II transcription

The RecQ family of helicases are traditionally viewed as recombination factors, important for maintaining genome stability. RECQL5 is unique among these proteins in being associated with RNA polymerase II, the enzyme responsible for transcribing all protein-encoding genes in eukaryotes. Here, we describe the possible implications of recent studies and discuss models for RECQL5 function.
