Sequence comparison of the 5' ends of human GCNF cDNAs coding for a full-length protein with the genomic DNA sequence. The genomic sequence NT_008491 is shown in the upper lines as indicated. Human cDNA sequences have been aligned omitting the cloning sites at the 5' ends. Accession numbers are shown. One cytosine and five adenosines in the genomic sequence not found in any of the cDNAs are underlined. Nucleotides in the cDNAs that differ in additional positions are highlighted in bold letters. The deduced amino-acid sequences (AAB50876, AAC52054) are given in the single-letter code.
