Fourier transform infrared(FTIR)microspectroscopy was used to investigate the effects of C-terminal acidic protein on the secondary structure of wheat α-thionin in the absence of signal peptide during the prokaryotic expression process.

Studies of site directed mutagenesis and chimeric receptors have indicated that the N terminus region of CCR5 is important for chemokines binding, viral fusion, and entry.

Many experiments showed that mRNA transcriptional termina-tion was involved in the carboxy-terminal domain (CTD) of the largest subunit of RNA polymerase II, severaltranscriptional termination related factors and their interaction.
