The SLD3 DNA replication regulator is required for loading and maintenance of Cdc45 on chromatin during DNA replication [2]. This entry represents the SLD3-Treslin domain (STD), which is shared with treslin, the metazoan counterpart, which differ in size and amino acid sequence [3-5]. According to their similarities, it has been suggested that helicase activation in mammals has diverged in complexity during evolution from that in yeasts and may involve additional partners that interact with TopBP1 [3-5].
