RecQL1 (Q1N3) Mouse mAb #4839

The RecQ family is a group of DNA helicases that play an important role in global genomic stability (1). Mutations in three of the five known human RecQ proteins (BLM, WRN and RECQL4) give rise to clinically distinct disorders that are characterized by features such as premature aging and predisposition to cancer (2,3). The clinical distinction of each disease associated with these mutations points to distinct roles that members of this helicase family play in DNA metabolism. RecQL1 is the most abundant protein of the RecQ family and was the first family member to be discovered. No disease associations have been reported with RecQL1 and its biological activities are not well understood (4). It has recently been shown that depletion of RecQL1 negatively affects genomic maintenance and cellular proliferation – which may point to a role in DNA damage repair and cell cycle progression (5,6). Upregulation of RecQL1 along with other RecQ family members has been reported in cells in response to oncogenic viral infection (7).
