Abstract

A cloning vector comprises a replication system from a bovine papilloma virus, a regulatory system including the promoter and terminator from a human metallothionein II gene, and a prokaryotic replication system. The vector is useful for transforming mammalian cells where it is maintained as an automonously replicating episome. Transcription may be regulated by the presence of heavy metals and/or glucocorticoid hormones in the growth media.
