| Abstract | The surface distributions of three different membrane integral proteins, beta2-microglobulin (part of the histocompatibility antigen complex), aminopeptidase (alpha-aminoacyl-peptide hydrolase; EC 3.4.11.2), and the Na+,K+-ATPase (ATP phosphohydrolase; EC 3.6.1.3) on human fibroblasts grown in monolayer culture have been studied with their specific antibodies by immunofluorescence. On the same cells, the distribution of intracellular actin was observed by a spectrally distinct fluorescent staining procedure. If each of the antibody reagents was permitted to cluster its specific protein in the plane of the membrane, these clusters apparently became linked, through the membrane, to actin- and myosin-containing filaments (stress fibers) underneath the membrane, and were thereby immobilized. From these and other experiments, it appears that most, if not all, integral proteins can, upon clustering, form such transmembrane linkages to actin and myosin. A molecular mechanism for the formation of these linkages is proposed which postulates that actin is associated with the cytoplasmic surface of plasma membranes by peripheral attachment to a ubiquitous integral protein X in the membrane; when other integral proteins are induced to form clusters, they become bound to X and hence to actin (and myosin). The possible physiological role of these transmembrane linkages is briefly discussed. |

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.
