12.5kb genomic fragment encompassing the Clamp coding region and putative upstream regulatory regions (from BAC clone CH322-20C6).
Position of rescue fragment on reference sequence inferred from reported primer sequences.
Clamp+tCH322-20C6 rescues Clamp2
The homozygous lethality of Clamp2 mutants is rescued by combination with a single copy of Clamp+tCH322-20C6.
