ATP-dependent DNA helicase Q1 (UniProt: P46063; also known as EC:3.6.4.12, DNA helicase, RecQ-like type 1, RecQ1, DNA-dependent ATPase Q1, RecQ protein-like 1) is encoded by the RECQL (also known as RECQ1, RECQL1) gene (Gene ID: 5965) in human. RecQ helicases are a ubiquitous family of DNA unwinding enzymes involved in the maintenance of chromosome stability. They participate in various types of DNA repair, including mismatch repair, nucleotide excision repair and direct repair. Five members of the RecQ family have been reported in human cells: BLM, RECQ1, RECQ4, RECQ5, and WRN. RecQ1 displays high expression in heart, lung, skeletal muscle and kidney. It is also highly expressed in tumor cells and although brain exhibits low level of EecQ1, its expression is dramatically increased in human glioblastoma. Depletion of RecQ1 affects proliferation of glioblastoma cells and causes an increase in the level of DNA damage. RecQ1 depleted tumor cells are shown to be more sensitive to anti-tumor agents, such as hydroxyurea and temozolomide.
