ABSTRACT Improved secretion of heterologous proteins by hosts such as yeast by using promoters of at most intermediate strength with heterologous DNA secretion signal sequences is disclosed. A promoter of at most intermediate strength, such as the actin (ACT) or iso-l-cytochrome c (CYCl) promoter in S. cerevisiae is operatively linked to a DNA signal sequence, such as the MF.alpha.l signal sequence. A DNA sequence for a selected protein, such as somatomedin C (SMC), tissue plasminogen activator (TPA) or tumor necrosis factor (TNF), may be operatively linked to the DNA signal sequence.
