Each operon has some genes which encode cytoplasmic rather than membrane spanning chemoreceptors.
It consists of columnar epithelium but the individual cells lack cytoplasmic mucin although they are able to secrete mucin.
The affinity between other cytoplasmic protein tyrosine phosphatase, catalytic domains, and the SH2 domains of SHP-1 and SHP-2 will also be analyzed.
