Fig. 3From: Fhl1p protein, a positive transcription factor in Pichia pastoris, enhances the expression of recombinant proteinsAnalysis of differential gene expression of the 4 pel/AF in comparison to 4 pel strain. Red arrows (↑) indicate an increasing and green arrows (↓) indicate a decreasing of the corresponding transcriptional levels in the methanol induction phaseBack to article page
