SitCon (SITe CONservation) is a tool designed to explore conservation of functionally important sites in a series of hypothetically homologous candidate protein structures, and predict the function of a test protein whose aminoacid sequence is used as input. SitCon can also predict the presence of metal containing heterogroups and allows the visual comparison of binding site conservation between candidate and test proteins. This makes the tool useful also for analysis of proteins with known function.The algorithm used is not based on specific protein signatures, it works well even with very low homology candidate molecules thus allowing the detection of overlooked relationships between proteins.





Nanotechnology is being applied to cancer in two broad areas: the development of nanovectors, such as nanoparticles, which can be loaded with drugs or imaging agents and then targeted to tumours, and high-throughput nanosensor devices for detecting the biological signatures of cancer. Combined, such technologies could lead to earlier diagnosis and better treatment for patients with cancer.
