Talin is a high-molecular-weight cytoskeletal protein, localized at cell-extracellular matrix associations known as focal contacts. In these regions, talin is thought to link integrin receptors to the actin cytoskeleton. Talin plays a key role in the assembly of actin filaments and in spreading and migration of various cell types. Talin proteins are found in a wide variety of organisms, from slime molds to humans. The human Talin (HGMW-approved symbol TLN) gene was previously mapped to chromosome 9p, but little was known of its sequence and genomic structure. To characterize human TLN further, we have isolated a single bacterial artificial chromosome clone, harboring the entire gene. The gene extends over more than 23 kb and consists of 57 exons. We have localized TLN to human chromosome band 9p13 by both fluorescence in situ hybridization and radiation hybrid mapping. Northern blot analysis detected TLN expression in various human tissues, including leukocytes, lung, placenta, liver, kidney, spleen, thymus, colon, skeletal muscle, and heart. Based on its chromosomal location, expression pattern, and protein function, we considered TLN as a candidate gene for cartilage-hair hypoplasia (CHH), an autosomal recessive metaphyseal chondrodysplasia, previously mapped to 9p13. We sequenced the entire TLN coding sequence in several CHH patients, but no functional mutations were detected.
