| Abstract | Phospholipase C-gamma 1 (PLC-gamma 1; EC 3.1.4.11) hydrolyzes phosphatidylinositol 4,5-bisphosphate to generate diacylglycerol and inositol 1,4,5-trisphosphate and is activated in response to growth factor stimulation and tyrosine phosphorylation. Concomitantly, the enzyme translocates from the cytosol to the particulate cell fraction. A similar process of activation-induced translocation from the cytosol to the cell particulate fraction has also been described for protein kinase C (PKC). We have previously shown that activated PKC binds to specific receptor proteins, receptors for activated C kinase, or RACKs, of approximately 30 kDa. Here, we show that PLC-gamma 1 bound to these RACKs and inhibited subsequent PKC binding to RACKs. However, unlike PKC, the binding of PLC-gamma 1 to RACKs did not require phospholipids and calcium. After epidermal growth factor treatment of intact A-431 cells, the binding of PLC-gamma 1 to RACKs increased as compared with PLC-gamma 1 from control cells. This increase in PLC-gamma 1 binding to RACKs was due to the phosphorylation of PLC-gamma 1. Additional data indicated that PLC-gamma 1 binds to RACKs in solution; epidermal growth factor receptor-dependent PLC-gamma 1 phosphorylation and activation decreased in the presence of RACKs. It is possible that, in vivo, PLC-gamma 1 associates with RACKs or with other PLC-gamma 1-specific anchoring proteins in the particulate cell fraction. Since a PKC C2 homologous region is present in PLC-gamma 1, the C2 region may mediate the activation-induced translocation of the enzyme to the cell particulate fraction and the anchoring protein-PLC-gamma 1 complex may be the active translocated form of PLC-gamma 1. |

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.
