Tenascin (TN) is a hexameric extracellular matrix glycoprotein that is highly expressed in solid tumors but has a restricted distribution in normal adult tissues. Each TN subunit is composed of segments with high homology to the sequences of epidermal growth factor, fibronectin and fibrinogen. Furth

β¦ Synopsis
A 353-bp region encoding for the NH2 terminus of the noncollagenic part of the alpha 1(V) chain was amplified by the polymerase chain reaction (PCR), subcloned and sequenced. The subcloned PCR product (pGC1) presented the same nucleotide sequence as the original fragment from the published sequence of COL5A1. In situ hybridization, using pGC1 as a probe, mapped the COL5A1 gene to chromosome 9q34.3. This assignment shows that COL5A1 is not synthetic with COL5A2, which is localized together with other collagen genes on chromosome 2.

The human cytidine-5'-triphosphate synthetase (CTPS) gene was mapped by a direct mapping system combined with fluorescence in situ hybridization and replicated prometaphase R-bands. By high-resolution banding analysis, the signals were localized to band 34.1-34.3 of the short arm of chromosome 1; 1p
A recombinant probe specific for the pro alpha 2 chain of human Type V collagen has been used for the localization of the corresponding gene (COL5A2) to chromosome 2. Regional mapping by in situ hybridization and analysis of DNA from human X rodent cell lines indicated that COL5A2 is confined within
