| Abstract | Matrix metalloproteinases (MMPs) are a family of enzymes dependent on metal ion cofactors that cleave the proteins found in the extracellular matrix and proteins involved in signalling processes in humans. These proteins play many important roles in normal physiology and development, but under pathological conditions, disregulated MMP activity can lead to cancer progression, undesired inflammation, and numerous other conditions [1]. Biological inhibitors of MMPs in the form of antibodies offer an appealing method for disrupting MMP enzyme activity, as antibodies are capable of potently, specifically inhibiting individual MMPs [2] in ways that traditional small molecules cannot [3]. The key challenge in establishing antibody-based inhibition as a general strategy for interfering with the pathologic functions of MMPs is the lack of fundamental information relating the amino acid sequences of inhibitory antibodies to their unique properties as inhibitors. In this poster, we present a method for analyzing protein sequences to uncover salient features of sequences of antibodies capable of binding to and inhibiting MMPs. The method consists of the following steps. First, we number antibody sequences [4] and divide them into frameworks [6], scaffolds that shape the antibodies' overall structures, and complementarity determining regions (CDRs) [5], peptide loops that directly contact the target MMP or other biological target. Second, we extract frameworks and CDRs [7] from the sequences. Third, we identify the most distinguishing features of antibody utilizing feature selection and machine learning algorithms. We expect to find distinct features of antibodies that bind or inhibit MMPs with this method. Distinct features can be further experimentally evaluated by altering the features unique to MMP-binding or MMP-inhibiting antibodies to assess their importance. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
