This entry represents a BRCT domain found in TopBP1 (also known as DNA topoisomerase II-beta-binding protein 1) and SLF1 (SMC5-SMC6 complex localization factor protein 1). TopBP1 functions in DNA replication and damage response. It binds double-stranded DNA breaks and nicks as well as single-stranded DNA [1]. SLF1 plays a role in the DNA damage response (DDR) pathway by regulating postreplication repair of UV-damaged DNA and genomic stability maintenance [2]. This entry corresponds to the eight BRCT domain of TopBP1 and the second one in SLF1.	Domain
