Abstract:
We have constructed a transcription map covering a 2 Mb region beginning approximately 1 Mb distal to HLA-F. Cosmids isolated from a chromsome 6 library were positioned by YAC hybridisation, STS and fingerprint analysis. Using direct cDNA selection, exon trapping, and direct genomic sequence analysis, we identified 42 potential exonic fragments in this region. Six fragments corresponded to previously characterised genes, four previously broadly mapped to this region. Five fragments were similar to known genes, eight fragments matched ESTs and 10 of the remaining 23 novel fragments, gave a positive signal on northern analysis. All cDNA fragments were mapped to the YAC and cosmid contig covering the region and with respect to other known genes and STS in this area. The distribution of the cDNA fragments indicated their organisation in three clusters around CpG islands.
