New Advances and Results on Mathematical Genomics

Abstract: In our Home of Mathematical Genomics ( we started working with Human Olfactory Receptors (OR). In my presentation talk I will start with our OR model. Then, described below are proposed methods for the classification of a group of related proteins into subgroups based on their structures.  This finer classification will help to develop hypothesis concerning the functions of the proteins.  Similarly, analysis of their gene sequences would help to track the path of their evolution.

Classification of proteins

Methodology 1: Classification of n-variable Boolean Function and their Application

A.     Classification of Boolean functions

B.     Application of Boolean functions of each class to bring out similarities and dissimilarities between the proteins under study

Methodology 2: Generating Indicator Matrix and Its Quantification of Amino Acid Sequence

Methodology 3: Finding Similarities and Dissimilarities between Three Dimensional Structures of Two Proteins Using Mathematical Morphology
