Life in Nebraska is peaceful. In early spring, we have the annual migration of sandhill cranes and waterfowls through central Nebraska. We enjoy seasonal food from Farmers' Markets. In winter, we have crystal clear blue skies and dry cool air, which resemble space environments. Despite such a quiet neighborhood, our studies in Biological Sciences are exciting. Thanks to my colleagues and friends, I am enjoying science, touching and watching lives.
In our body, numerous metabolic chemical reactions are taking place. Proteins play a role in many chemical reactions. Hence, proteins are working as molecular machineries at the scene of life activities. Protein molecules interact with other molecules and change their shape during the process. My interest lies in how much energy is needed to change the shape, and in what is the meaning in organisms?
Leaving Japan, I arrived at the University of Nebraska-Lincoln in June 2002 as an Associate Research Professor in the Chemistry Department and the Center for Biotechnology. I moved to the School of Biological Sciences in August 2008 as an Associate Professor. Since then I have been studying proteins in an attempt to answer the above question. Since the function of a protein is determined by its shape, I have been using the protein crystallography as a microscope. It is including three properties of light, including energy, time, and phase. Since the shape of a protein is determined by its amino acid sequence, I have been taking idea of molecular evolution and population genetics.
In my studies, I will discuss about biological phenomena at the elementary level. For instance, when we investigate the fertilization barrier in terms of speciation, I chose marine invertebrates due to the visibility and simplicity. With a long-term collaboration of Dr. Midori Matsumoto at Keio University, we have been addressing roles of substances, including proteoglycans, steroids and peptide hormones, in fertilization of starfish. Although, I am studying many different proteins, hemoglobins and olfactory receptors became the center of my interests because of their critical roles in our body.
Hemoglobin carries oxygen in red blood cells. When the supply of oxygen becomes less than necessary in any part of boy, hypoxia symptom develops. Hemoglobin plays pivotal roles in these phenomena. In the study of hypoxia adaptation with hemoglobin, with Dr. Jay F. Storz, we are making a beautiful marriage between structural biology and population genetics.
Olfactory Receptors accept odor molecules and convert the stimulation into a nerve impulse, which is transmitted to the brain. The protein is located in the membrane. Therefore, structural studies are remaining the challenge. However, these studies will give the structural framework of other receptors, including CD4 and CD 155, which accept HIV and poliovirus, respectively. Collaborations with Dr. Etsuko Moriyama encourage me to continue work.
Finally, all sciences are corroborative efforts. No one can do everything. No part can be lacked to achieve the work. This is my motto. I appreciate my colleagues. Studies on male-female interactions at the protein level with Dr. Lawrence Harshman are exciting. Dr. Catherine P. Chia has introduced a very funny organism, slime mold, to me.
My science has been supported by Nebraska Tobacco Settlement Biomedical Research Development Funds, the National Institute of Health, the National Science Foundation, and the University of Nebraska-Lincoln.
