内容:

High-throughput sequencing has been producing a large amount of protein sequences, but many of them are missing solved structures and functional annotations, which are essential to the understanding of life process and diseases and also have tremendous implications to drug discovery and design. This talk will focus on data-driven computational methods for the elucidation of protein structure and function and evolutionary relationship. In particular,this talk will present the modeling of multiple protein sequence alignment (MSA) by probabilistic graphical models (e.g., joint graphical lasso) and its application to a few challenging problems including protein remote homology detection, evolutionary coupling analysis and protein contact prediction. The technical details are described in the following two papers:http://bioinformatics.oxfordjournals.org/content/early/2015/08/14/bioinformatics.btv472 and http://www.ploscompbiol.org/article/info%3Adoi%2F10.1371%2Fjournal.pcbi.1003500  .
