CNTF Protein Overview: Sequence, Structure, Function and Protein Interaction

CNTF Protein Overview

By analysis of human-hamster somatic cell hybrids, Lam et al. (1991) mapped the CNTF gene to chromosome 11. Using a rodent/human somatic cell DNA mapping panel and fluorescence in situ hybridization, Lev et al. (1993) localized the CNTF gene to the proximal region of 11q. In addition, they identified a polymorphic tandem CA/GT dinucleotide repeat associated with the human CNTF gene. To sublocalize the CNTF gene on chromosome 11, Giovannini et al. (1993) isolated cosmid clones containing the gene by use of a chromosome 11-specific library. Using these clones in fluorescence in situ hybridization, they found that the gene maps at an FLpter of 0.46, corresponding to a cytogenetic band position of 11q12.2, according to the method of Lichter et al. (1990). Yokoji et al. (1995) isolated a full-length cDNA for human ciliary neurotrophic factor from a sciatic nerve cDNA library, determined its structure, and localized it to chromosome 11q12 by fluorescence in situ hybridization. Kaupmann et al. (1991) demonstrated that the mouse Cntf gene is on mouse chromosome 19 and that its expression is unaffected in the mouse neurologic mutant wobbler (see 614633), a form of spinal muscular atrophy.
