Abstract
An expression method for enhanced recombinant production of a desired protein due to the presence of lactation-signals is provided which comprises cells transformed with a DNA sequence having the desired protein coding sequence under the control of a bovine prolactin promoter and a bovine prolactin distal enhancer sequence. A preferred embodiment uses growth hormone sequences as the desired protein coding sequences. In this embodiment, feed-efficiency of milk-producing animals is improved.
