| Abstract | The histone code hypothesis predicts that the post-translational modification of histones can bring about distinct chromatin states, and it therefore serves a key regulatory role in chromatin biology. The impact of one mark on another has been termed cross-talk. Some marks are mutually exclusive, while others act in concert. As multiple marks contributing to one outcome are generally brought about by complexes containing multiple catalytic and binding domains, it appears regulation of chromatin involves a web of writers and readers of histone modifications, chromatin remodeling activities and DNA methylation. Here, we focus on the protein lysine methyltransferases G9a and GLP as examples of this extended cross-talk. G9a and GLP can catalyze the formation of and bind to the same methyl mark via distinct domains. We consider the impact of other histone modifications on G9a/GLP activity and the coordination of activities within G9a/GLP containing complexes. We evaluate the potential impact of product binding on product specificity and on maintenance and propagation of the methyl mark. Lastly, we examine the recruitment of other silencing factors by G9a/GLP. Regulated assembly of specific complexes around key marks may reinforce or alter the biological outcome associated with given histone modifications. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
