Mapping of human and murine genes for latent TGF-beta binding protein-2 (LTBP2).
A novel gene, isolated because of structural similarities to fibrillin, was called LTBP2 when its 4.6-kb transcript was found to encode a protein sequence related to the latent TGF-beta binding protein (LTBP1), which is encoded on human chromosome (Chr) 2, region p12-q22. We have assigned the human and murine LTBP2 loci to regions of conserved synteny on human Chr 11 and mouse Chr 19. By PCR analysis of somatic cell hybrid DNA and fluorescence in situ hybridization, LTBP2 was mapped to human Chr band 11q12 and Ltbp2 to mouse Chr band 19B. Differences between inbred strains were discovered by single-strand conformation analysis of PCR products from the 3' untranslated region. Analysis of BXD and AKXL recombinant inbred strains have placed Ltbp2 between D19Rp19 and Ly10 on proximal mouse Chr 19.
