| Abstract | Nucleosomes regulate transcriptional initiation when positioned in the promoter area. This may require the transcription factor (TF) sites to be correlated with the nucleosome positions and phased on the nucleosome surface. If this is the case, one would expect a periodical distribution of TF sites in the vicinity of promoters, with the nucleosomal period of 10.1-10.5 bp. We examined the distributions of putative binding sites of 323 different TFs along 1, 057 sequences of the Eukaryotic Promoter Database (release 50) [Cavin Perier, R., Junier, T. & Bucher, P. (1998) Nucleic Acids Res. 26, 353-357] and of 218 TFs on 673 sequences of the Lead Exon Database of human promoter sequences. We obtained a statistically significant overrepresentation of TF sites distributed with the main period of 10.1-10.5 bp in the region -50 to +120 around the transcription start site and in few locations nearby. Correlation of the positioning of the TF sites with the nucleosomes is further reinforced by sequence-directed mapping of the nucleosomes, a method previously developed. |

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.
