| Abstract | Interferon (IFN) induces transcription of major histocompatibility class I genes by way of the conserved cis-acting regulatory element, termed the IFN consensus sequence (ICS). Binding of nuclear factors to the ICS was studied in gel mobility shift assays with the 5' upstream region of the murine H-2Ld gene. We found that the ICS binds a constitutive nuclear factor present in lymphocytes and fibroblasts regardless of IFN treatment. Within 1 hr after IFN treatment, new ICS binding activity was induced, which consisted of at least two binding activities distinguished by their requirement for de novo protein synthesis. Methylation interference and competition experiments showed that both constitutive and induced factors bind to the same approximately equal to 10-base-pair binding site within the ICS. Site-directed mutagenesis of H-2Ld-chloramphenicol acetyltransferase fusion genes showed that mutations in the binding site, but not in other regions of the ICS, abolish transcriptional activation of class I genes by IFN, providing evidence that specific binding of nuclear factors to the ICS is an essential requirement for transcriptional induction. Finally, we show that IFN-inducible genes of various species share a sequence motif that is capable of competing for the nuclear factors identified here. We propose that specific protein binding to the conserved motif represents a basic mechanism of IFN-mediated transcriptional induction of a number of genes. |

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.
