Transcriptional control of the human leucocyte common antigen

Objective



The project aims to identify transcriptional control elements of the human leucocyte common (CD45) antigen. Because of the large size of the human CD45 gene, we shall take advantage of the much smaller genome size of the Japanese puffer fish, Fugu rubripes. We shall clone the Fugu CD45 homologue by low stringency hybridisation screening of a splenic cDNA library or amplification of leucocyte cDNA using degenerate oligos. The Fugu CD45 cDNA will be used to probe a cosmid genomic library and the gene will be cloned and sequenced. Likely transcriptional control sequences will be identified by sequence analysis, subcloned into CAT vectors and tested for promoter and enhancer activity by transfection into Iymphoid and nonIymphoid lines. The human homologues of transcriptional control regions will be identified, cloned and tested by similar methods. Human tissue specific elements will also be tested in vivo by construction of transgenic mice.
Training content (objective, benefit and expected impact)
The proposed project will provide training in a range of molecular biology methods and in the analysis of gene expression using transient transfection assays and transgenic mice. It will provide information on the control of expression of an important gene product of leucocytes, perhaps Ieading to new insights into how differentiation of leucocytes is regulated.
Links with industry / industrial relevance (22)
The Edward Jenner Institute for Vaccine Research will discuss with Glaxo Wellcome the commercial exploitation of any patentable discoveries arising from this project.
