Abstract excerpt
The 70-kDa heat shock proteins are molecular chaperones that participate in a variety of cellular functions. This chaperone function is stimulated by interaction with hsp40 proteins. The Saccharomyces cerevisiae gene encoding the essential hsp40 homologue, SIS1, appears to function in translation initiation. Mutations in ribosomal protein L39 (rpl39) complement loss-of-function mutations in SIS1 as well as PAB1...
