Heterologously expressed polypeptide from the yeast meiotic gene HOP1 binds preferentially to yeast DNA.

HOP1 protein, present in sporulating cells of Saccharomyces cerevisiae and believed to be a component of the synaptonemal complex, has been expressed in Escherichia coli fused to a biotinylated tag protein. Once solubilized from bacterial inclusion bodies, the HOP1 fusion protein was purified by using a combination of avidin-affinity chromatography and gel… CONTINUE READING
