Scientific background: |
SFTPC(Surfactant pulmonary -associated protein C), also known as SFTP2, SPC, PSP-C or PULMONARY SURFACTANT PROTEIN SP5, is a protein that in humans is encoded by the SFTPC gene. It is a membrane protein which manufactures surfactant. Glasser et al. (1988) assigned the SFTPC gene, symbolized SFTP2 by the Human Gene Mapping nomenclature committee, to chromosome 8 by hybridization to somatic cell hybrid DNA. Wood et al. (1994) identified 4 cosmids at the SFTP2 locus by cDNA hybridization. Using a polymorphic CA repeat in the SFTP2 gene and linkage analysis in 8 CEPH families, they located the gene close to D8S298; maximum lod = 19.3 at theta = 0.01. They regionalized the gene to 8p21 by fluorescence in situ hybridization. Moore et al. (1992) showed that the corresponding mouse gene, Sftp2, maps to chromosome 14. |
