The CCND1-EMS1 locus on human chromosome 11q13 is amplified in esophageal cancer, bladder tumors, and breast cancer. During analyses of FGF gene cluster within the CCND1-EMS1 locus, we identified a 5'-truncated partial cDNA (NM_018043.1) derived from the uncharacterized FLJ10261 gene. Here, we characterized the FLJ10261 gene by using bioinformatics. NM_018043.1 cDNA corresponded to the nucleotide position 1129-4258 of 4558-bp DKFZp686O1156 cDNA, and the nucleotide position 50-3010 of DKFZ-p686O1156 was the coding region of the FLJ10261 gene. FLJ10261 gene, consisting of 26 exons, was located between FGF3 and FADD genes within the CCND1-EMS1 locus. Two FLJ10261 isoforms with or without exon 15 were transcribed due to alternative splicing. FLJ10261 mRNA was expressed in head and neck tumors, parathyroid tumors, breast, pancreatic, and gastric cancer. Mouse Flj10261 gene (AK052589) was located between Fgf3 and Fadd genes on mouse chromosome 7. Human FLJ10261 gene was homologous to C12orf3 gene on human chromosome 12p13, C11orf25 gene on 11p14, and FLJ34272 gene on 12q23. Human FLJ10261 protein showed 89.8% total-amino-acid identity with mouse Flj10261 protein, and also 58.4%, 38.3%, and 38.6% identity with human C12orf3, C11orf25, and FLJ34272/BAC03704 proteins, respectively. FLJ10261, C12orf3, C11orf25 and FLJ34272 proteins were eight-transmembrane proteins with N- and C-terminal tails facing the cytoplasm, which might function as transporters for unidentified substrates. This is the first report on comprehensive characterization of the FLJ10261 gene located within the CCND1-ORAOV1-FGF19-FGF4-FGF3-FLJ10261-FADD-PPFIA1-EMS1 locus on human chromosome 11q13.

The CCND1-ORAOV1-FGF19-FGF4-FGF3-FLJ10261-FADD-PPFIA1-EMS1 locus on human chromosome 11q13 is frequently amplified in esophageal cancer, breast cancer, and bladder tumors. FGF19, FGF4 and FGF3 genes are implicated in embryogenesis and carcinogenesis. We proposed in 2002 the hypothesis that mouse Fgf15 might be the ortholog of human FGF19 based on comparative genomics. Here, we identified zebrafish fgf19 and oraov1 genes by using bioinformatics to demonstrate the hypothesis. Zebrafish fgf19 gene, consisting of three exons, was located around nucleotide position 121802-124963 of zebrafish genome draft sequence AL929586.12 in the reverse orientation. Zebrafish fgf19 (209 aa) was more homologous to chicken fgf19 and human FGF19 than to rodent Fgf15. Zebrafish oraov1 gene, consisting of five exons, was located around nucleotide position 112172-115838 of AL929586.12 in the reverse orientation. Zebrafish oraov1 protein (141 aa) was more homologous to human ORAOV1 than to rodent Oraov1. The CCND1-ORAOV1-FGF19-FGF4 locus was well conserved between human and zebrafish genomes in the order of genes, in the direction of genes, and in the exon-intron structure. Rat Ccnd1-Oraov1-Fgf15-Fgf4 locus was synthenic to mouse Ccnd1-Oraov1 (also known as 2210010N10Rik)-Fgf15-Fgf4 locus. Fgf15, homologous to human FGF19 and zebrafish fgf19, was located on the synthenic locus of human FGF19 and zebrafish fgf19 within rodent genomes. Based on the evolutionary conservation of the CCND1-ORAOV1-FGF19-FGF4 locus from zebrafish to human, it was concluded that Fgf15 gene is the rodent ortholog of human FGF19 gene.

The CCND1-ORAOV1-FGF19-FGF4-FGF3-TMEM16A-FADD-PPFIA1-CTTN (EMS1) locus at human chromosome 11q13.3 is amplified in head and neck tumors, esophageal cancer, Kaposi's sarcoma, bladder tumors, breast cancer, and liver cancer. Fgf4 mRNA is expressed in embryonic stem (ES) cells depending on Sox2 and Pou5f1 (Oct3/Oct4) transcription factors, and in myotomes and limb bud AER depending on MyoD (or Myf5) and GATA transcription factors. Here, rat Fgf3 and Fgf4 complete coding sequences were determined by using bioinformatics. Multiple errors, including one-base insertion and 22-base deletion, were identified within the coding region of rat Fgf4 RefSeq (NM_053809.1 or AB079673.1). Rat Fgf3 and Fgf4 genes, consisting of three exons, were clustered in tail-to-head manner with an interval of about 16 kb. CUTL1 (CCAAT-displacement protein, CDP) and NKX2-5 binding sites and TATA box within 5'-flanking promoter region were conserved among human, rat and mouse Fgf3 orthologs. MYOD and MYOG (Myogenin) binding sites and TATA box within 5'-flanking promoter region as well as GATA, MYOD, SOX2 and POU5F1 binding sites within exon 3 were conserved among mammalian Fgf4 orthologs. Human FGF3 and FGF4 genes were clustered in tail-to-head manner with an interval of about 35 kb. Major repetitive sequence (FGF34Rep1) and minor repetitive sequence (FGF34Rep2) were identified within human FGF3-FGF4 gene cluster. FGF34Rep1 were clustered within the FGF3-FGF4 locus as well as around the IL28RA locus (1p36.11) and the NFAM1 locus (22q13.2). FGF34Rep2 was characterized by the CCA(T/C) repeats. This is the first report on comparative genomics analyses on the Fgf3-Fgf4 locus within human, rat and mouse genomes.
