摘要
Southern analysis using a human glycine decarboxylase cDNA probe and genomic DNA preparations from Chinese hamster human hybridoma cell lines demonstrated that on the segregated human chromosomes, 4 and 9, there are glycine decarboxylase cDNA-related sequences. The finding is confirmatory of the fact that fragments of both the true and processed genes for this protein have been cloned. Since one of four HindIII fragments revealed in the present Southern analysis matched requirements for the property expected from the restriction map reported for the processed gene, this was located on chromosome 4. The three remaining signals were consequently ascribed to fragments from the true gene on chromosome 9. Fluorescence in situ hybridization using the genomic clones assigned the true and processed genes to 9p23-24 and 4q12, respectively.
