Description
Transient receptor potential channels (TRP channels) are a family of ion channels that mediate a wide variety of sensations, including pain, temperature, and mechanosensation. Human phosphoinositide-interacting regulator of TRP (hPIRT) is a 15.5 kDa, relatively uncharacterized membrane protein that has been shown to modulate the activity of certain TRP channels and some other ion channels. hPIRT is also able to interact with phosphatidylinositol-4,5-bisphosphate (PI(4,5)P¬2), a phospholipid that modulates the activity of many important signaling proteins, including TRP channels. Some information is already known about the structure of hPIRT: it contains a relatively unstructured N-terminus, two transmembrane helices, and a juxtamembrane region at the C-terminus that plays a role in binding PI(4,5)P2 and TRPV1. However, more detailed structural data about this molecule would be very informative in understanding how these interactions occur. In order to accomplish this, this thesis investigates the measurement of residual dipolar couplings (RDCs) in nuclear magnetic resonance spectroscopy (NMR) to refine the structure of hPIRT. RDCs are a measurable effect in NMR experiments caused by partial alignment of molecules solubilized in a weakly anisotropic medium. The resulting data set can be used to calculate bond angles within the protein relative to the axis of the external magnetic field, which will assist efforts to further constrain the structure of hPIRT.

Description
Human Papillomavirus, or HPV, is a viral pathogen that most commonly spreads through sexual contact. HPV strains 6 and 11 normally cause genital warts, while HPV strains 16 and 18 commonly cause cervical cancer, which causes cancerous cells to spread in the cervix. Physicians can detect those HPV strains, using a Pap smear, which is a diagnostic test that collects cells from the female cervix.

Description
Johann Gregor Mendel studied patterns of trait inheritance in plants during the nineteenth century. Mendel, an Augustinian monk, conducted experiments on pea plants at St. Thomas’ Abbey in what is now Brno, Czech Republic. Twentieth century scientists used Mendel’s recorded observations to create theories about genetics.
