Abstract:
Rat olfactory epithelium and ciliar cytosol of olfactory cells contained the water-soluble 45 kDa protein which was revealed by antibodies against a peptide fragment of the alpha-subunits common to the G-proteins. No analogous proteins were found in other rat tissues. According to the photo-affinity labeling, the 45 kDa protein possessed a high affinity to GTP; it also exhibited a low GTP hydrolytic activity.
