| Abstract | The filamentous/invasive growth pathway is activated by nutrient limitation in the haploid form of the yeast Saccharomyces cerevisiae, whereas exposure to mating-pheromone causes cells to differentiate into gametes. Although these two pathways respond to very different stimuli and generate very different responses, they utilize many of the same signaling components. This implies the need for robust mechanisms to maintain signal fidelity. Dse1 was identified in an allele-specific suppressor screen for proteins that interact with the pheromone-responsive Gβγ, and found to bind both to a Gβγ-affinity column, and to the shared MEKK, Ste11. Although overexpression of Dse1 stimulated invasive growth and transcription of both filamentation and mating-specific transcriptional reporters, deletion of DSE1 had no effect on these outputs. In contrast, pheromone hyper-induced transcription of the filamentation reporter in cells lacking Dse1 and in cells expressing a mutant form of Gβ that exhibits diminished interaction with Dse1. Thus, the interaction of Dse1 with both Gβ and Ste11 may be designed to control cross talk between the pheromone and filamentation pathways. |

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.
