Characterization of a SR protein from Trypanosoma brucei with homology to RNA-binding cis-splicing proteins.

abstract：:Schistosomes have a complex life cycle (vertebrate and molluscan hosts as well as larvae living freely in water) in which they are exposed to different environments and temperatures (20 degrees C - 37 degrees C). Since heat shock genes are activated in response to stress and during development [1], it is of interest t...
