Yeast has most of the characteristics of other eukaryotic cells, making it a better choice for expressing proteins from animal cells than prokaryotic E. coli. Yeast cells, like animal cells, have a nucleus and other organelles, allowing them to carry out post-translational modifications that may be necessary for proper protein folding and activity. Additionally, yeast can secrete proteins into the extracellular space, which may be desirable for certain applications.
