| Abstract | We have cloned a gene encoding a DNA-binding protein by Southwestern screening of a murine cDNA library with a double-stranded oligonucleotide containing the sequence from the bidirectional promoter of the alpha 1 and alpha 2 collagen IV genes. The middle portion of this 1131-amino acid protein has a region homologous to bacterial DNA ligases, and the more carboxyl portion contains several domains homologous to p40, p38, p37, and p36.5 subunits of activator 1 (A1, also called replication factor C), a human replication protein complex. Western blotting revealed that antiserum generated against part of the recombinant protein reacted specifically with the 145-kDa component of the purified human A1 complex, indicating that it is the murine counterpart of the A1 p145. Characterization of the DNA-binding activity of the recombinant fusion protein by gel mobility-shift assay revealed that it had a preference for a run of pyrimidines on one strand. Deletion analysis using recombinant proteins revealed that the DNA ligase-like domain was required for DNA-binding activity. The finding that the region required for the binding of murine A1 p145 to DNA has similarity to a domain found in DNA ligases suggests that this region may be utilized by both proteins in recognizing DNA. |

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.
