Tsr4 Is a Cytoplasmic Chaperone for the Ribosomal Protein Rps2 in Saccharomyces cerevisiae.

abstract：:Though widely recognized in higher eukaryotes, the regulation of Saccharomyces cerevisiae genes transcribed by RNA polymerase II by proteins that bind within the coding sequence remains largely speculative. We have shown for the LPD1 gene, encoding lipoamide dehydrogenase, that the coding sequence between +13 and +469...
