Abstract
An upstream activator sequence derived from the yeast PGK gene. The upstream activator sequence is contained in the 5' region of the yeast PGK gene between nucleotides -324 and -455. The upstream activator sequence has synthetic linkers attached to either end to facilitate attachment to a vector. Vectors including the upstream activator sequence and a heterologous promoter sequence are described. The upstream activator sequence is used in a method for increasing the expression level of a yeast expression vector.
