| Abstract | Class IIa histone deacetylases repress transcription of target genes. However, their mechanism of action is poorly understood because they exhibit very low levels of deacetylase activity. The class IIa HDACs are associated with the SMRT/NCoR repression complexes and this may, at least in part, account for their repressive activity. However, the molecular mechanism of recruitment to co-repressor proteins has yet to be established. Here we show that a repeated peptide motif present in both SMRT and NCoR is sufficient to mediate specific interaction, with micromolar affinity, with all the class IIa HDACs (HDACs 4, 5, 7, and 9). Mutations in the consensus motif abrogate binding. Mutational analysis of HDAC4 suggests that the peptide interacts in the vicinity of the active site of the enzyme and requires the “closed” conformation of the zinc-binding loop on the surface of the enzyme. Together these findings represent the first insights into the molecular mechanism of recruitment of class IIa HDACs to the SMRT/NCoR repression complexes. |

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.
