| Abstract | Among cell cycle regulatory proteins that are activated following DNA damage, the cyclin-dependent kinase inhibitor p21(CDKN1A) plays essential roles in the DNA damage response, by inducing cell cycle arrest, direct inhibition of DNA replication, as well as by regulating fundamental processes, like apoptosis and transcription. These functions are performed through the ability of p21 to interact with a number of proteins involved in these processes. Despite an initial controversy, during the last years several lines of evidence have also indicated that p21 may be directly involved in DNA repair. In particular, the participation of p21 in nucleotide excision repair (NER), base excision repair (BER), and DNA translesion synthesis (TLS), has been suggested to occur thanks to its interaction with proliferating cell nuclear antigen (PCNA), a crucial protein involved in several aspects of DNA metabolism, and cell-cycle regulation. In this review, the multiple roles of p21 in the DNA damage response, including regulation of cell cycle, apoptosis and gene transcription, are discussed together with the most recent findings supporting the direct participation of p21 protein in DNA repair processes. In particular, spatio-temporal dynamics of p21 recruitment to sites of DNA damage will be considered together with several lines of evidence indicating a regulatory role for p21. In addition, the relevance of post-translational regulation in the fate (e.g. degradation) of p21 protein after cell exposure to DNA damaging agents will be analyzed. Both sets of evidence will be discussed in terms of the overall DNA damage response. |

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.
