Welcome to my web site and feel free to contact me if there is something here that piques your interest. This is my 32nd year at Morehouse and I have had the good fortune to serve the institution in a number of capacities. I am currently the David Packard Professor in Science and teach a Cell Biology course and coordinate a Biological Research course in the Department of Biology. These courses are described in more detail in the Web Site. Teaching is my passion, and while as Dean of Science and Mathematics, no longer have to teach, will teach until I retire from the College.

profile I am no longer doing research, but I remain deeply interested in research on Hemoglobin S and sickle cell membranes, the topics on which I worked. I am also very interested in several other areas of cell biology namely the cytoskeleton and protein trafficking in cells. I have always attempted to integrate my research interests into the courses that I teach. From the very beginning of my career at Morehouse, I have served as both a faculty member and an administrator, which gives me a unique view of this institution from both sides of what many consider a significant divide. I have served as Director of the Office of Health Professions, Chair of the Department of Biology, and now as Dean of the Division of Science and Mathematics. All of these administrative experiences have deepened my commitment to assisting students in every way that I can towards maximizing their intellectual and personal development while students at the College.

profile Throughout my career at Morehouse,Dr. J.K. Haynes I have encouraged students to do research regardless of their career goal, because participation in research is a powerful way of developing problem solving and critical thinking skills, two of the most important goals of a liberal education. As Dean of the Division of Science and Mathematics, I have also encouraged students to seek a more interdisciplinary education, in recognition of the fact that the sciences are not separate in nature and the most interesting problems that we need to solve, such as renewable and clean energy, are inherently interdisciplinary. Finally, I continue to urge students to study and do research abroad, whether it be in South America, Africa or Europe. We live in a time where peoples from across the globe ore interacting in various ways, and we clearly need to be more knowledgeable about other cultures in order to gain the most from these interactions. More information about Division Initiatives can be found in our Cyber Village Website located at http://www.morehouse.edu/academics/cybervillage/index.html I hope that your visit to this Web Site will be informative.

Biochemical characterization of sickle cell membranes
Regulation of cell volume
The symptoms of sickle cell anemia are due primarily to vaso-occusions, which result from red blood cell membrane damage. We have detected several alterations in the protein composition of sickle cell membranes, including the appearance of a unique high molecular weight protein. Continuing investigations aim at further characterization of these protein alterations and determining whether they play a role in vaso-occlusions.A wide variety of cells have been shown to maintain their volume in anisosmotic medium by regulating the activity of specific membrane transport systems. In marine fishes and in vertebrates, membrane transport of organic osmolytes, particularly amino acids, is principally responsible for the regulation of cell volume. In elasmobranchs, the key organic osmolytes are the (-amino acids, taurine and (-alanine. We have shown that skate erythrocytes regain their volume after swelling in hypotonic medium by releasing taurine through a gated-membrane channel, whose size appears to be about 6 Ao in diameter. We have also studied osmoregulation in shark rectal gland cell cultures. Inhibitor studies suggest that a different protein is involved in taurine transport in these cells and that a tyrosine phosphoprotein is involved. The goal of future work is to further characterize the regulation and mechanism of action of osmoregulatory transport proteins.
