Formin homology proteins with FH1 and FH2 domains are signaling effectors for assembly and polarization of actin filaments. FH1 is the binding domain for Profilin, SRC, EMS1/Cortactin, FNBP1, FNBP2, FNBP3, FNBP4 and WBP4/Fbp21, while FH2 is the actin-filament modification domain. Here, we identified and characterized a novel member of Formin-homology gene family, Diaphanous homology 3 (DIAPH3), by using bioinformatics. DIAPH3 isoform 1, corresponding to 3'-truncated FLJ34705 cDNA and 5'-divergent IMAGE5265490 cDNA, encodes full-length DIAPH3 protein (1112 aa), while DIAPH3 isoform 2, identical to NM_030932.2 cDNA, encodes N-terminally truncated DIAPH3 protein (849 aa). DIAPH3 isoform 1, consisting of exons 1-27, was expressed in lymph node, erythroid progenitor cells as well as in pancreatic cancer. DIAPH3 isoform 2, consisting of exons 1b and 8-27, was expressed in testis. DIAPH3 gene at human chromosome 13q21.2 was found to encode two isoforms due to alternative splicing of the alternative promoter type. Full-length human DIAPH3 protein, consisting of FDD, FH1 and FH2 domains, showed 51.3% total-amino-acid identity with DIAPH1, and 57.3% total-amino-acid identity with DIAPH2. FMNL1/FMNL, FMNL2/FHOD2, FMNL3/WBP3, DAAM1, DAAM2, DIAPH1, DIAPH2 and DIAPH3 were classified as the FDD-type Formin homology proteins, while GRID2IP/Delphilin, FHOD1, Fmn1 and Fmn2 were classified as the non-FDD-type Formin homology proteins. This is the first report on identification and characterization of human DIAPH3 gene.

Mouse Formin (Fmn1) protein plays a key role in limb morphogenesis. Fmn1 is one of the actin regulators with scaffold function, interacting with Profilin, SRC, EMS1, FNBP1, FNBP2, FNBP3, FNBP4, WBP4 and alpha-catenin. Fmn1, Fmn2, FHOD1, FHOD3, GRID2IP and FHDC1 are non-FDD-type Formin homology proteins, while FMNL1, FMNL2, FMNL3, DIAPH1, DIAPH2, DIAPH3, DAAM1 and DAAM2 are FDD-type Formin homology proteins. Here, we identified the human FMN1 gene by using bioinformatics. The complete coding sequence of human FMN1 cDNA was determined by assembling AC055874.8 genome sequence (nucleotide position 178207-180073), AI040235 EST (complementary sequence for nucleotide position 331-156) and FLJ45135 cDNA (nucleotide position 319-3310). FMN1 isoform 1 (exons 1-18) and FMN isoform 2 (exons 1b and 3-18) were transcribed due to alternative splicing of the alternative promoter type. The FMN1 gene at human chromosome 15q13.3 was located between CKTSF1B1 (Gremlin) and RYR3 genes. The Xenopus fmn1 gene was identified within the Xenopus genome sequence CH216-24N20 (AC147835.1). The FMH1 domain (codon 1-120 of FMN1) and FMH2 domain (codon 683-835 of FMN1) were identified as novel regions conserved among human FMN1, mouse Fmn1, and Xenopus fmn1. The FMH2 domain was almost identical to the alpha-catenin binding domain of mouse Fmn1. Human FMN1 (1419 aa), showing 77.1% total amino-acid identity with mouse Fmn1, was found consisting of FMH1, FMH2, FH1 and FH2 domains. This is the first report on the identification and characterization of the human FMN1 gene as well as the FMH1 and FMH2 domains.

FNBP1, FNBP1L, CIP4/TRIP10, FNBP2, SRGAP1/ARHGAP13, SRGAP2/ARHGAP14, ARHGAP4, FCHSD1, and FCHSD2 constitute the FCFBS superfamily characterized by FES-CIP4 homology (FCH) domain, Formin-binding FNBP1-FNBP2 homology (FBH) domain, and SRC homology 3 (SH3) domain. During genome-wide searching for human genes encoding FCH domain molecules, we identified the FCHO2 gene by using bioinformatics. DKFZp451B033 (AL831971.1) was the representative cDNA derived from human FCHO2 gene, while FLJ32208 (AK056770.1) was a chimeric cDNA generated by the recombination between FCHO2 and CSH1 genes. MGC63242 (BC052456.1) rather than 5832424M12 (AK031041.1) was the representative cDNA derived from mouse Fcho2 gene. FCHO2 gene, consisting of 26 exons, was mapped to human chromosome 5q13.2. Human FCHO2 (810 aa) showed 94.6% total-amino-acid identity with mouse Fcho2 (809 aa), and 50.4% total-amino-acid identity with human FCHO1. Drosophila CG8176 (NP_788613.1) and C. elegans 2B609 (NP_493947.1) were homologs of mammalian FCHO2 and FCHO1. FCHO-homologous (FOH) domain (codon 527-810 of human FCHO2) was identified as the novel domain conserved among FCHO homologs. Human FCHO2, FCHO1, Drosophila CG8176 and C. elegans 2B609 were found consisting of N-terminal FCH domain and C-terminal FOH domain. This is the first report on identification and characterization of evolutionarily conserved FCHO homologs as well as the novel FOH domain.

Mouse Formin (Fmn1) is an actin regulator interacting with Profilin, SRC, EMS1, FNBP1, FNBP2, FNBP3, FNBP4, WBP4 and alpha-catenin. FMN1, FHOD1, FHOD3, GRID2IP and FHDC1 are non-FDD-type Formin homology proteins, while FMNL1, FMNL2, FMNL3, DIAPH1, DIAPH2, DIAPH3, DAAM1 and DAAM2 are FDD-type Formin homology proteins. Here, we characterized human FMN2 gene by using bioinformatics. Complete coding sequence of human FMN2 cDNA was determined by assembling AL359918, AL513342, AL590490, AL646016 genome sequences, AF218941 partial cDNA, and AF218942 partial cDNA. FMN2 mRNA was expressed in fetal brain, adult whole brain, hypothalamus, retina, pancreatic islet and germinal-center B cells. Among various human tumors, FMN2 mRNA was expressed in parathyloid tumor, glioblastoma, retinoblastoma and chondrosarcoma. Human FMN2 (1722 aa) showed 74.7% total-amino-acid identity with mouse Fmn2, and 31.9% total-amino-acid identity with human FMN1. Although N-terminal half was divergent between FMN2 orthologs and FMN1 orthologs, FH1 and FH2 domains were conserved among FMN2 and FMN1 orthologs. Exon-intron structure was conserved between FMN2 and FMN1 genes. RYR2-FMN2-CKTSF1B2 (PRDC) locus at human chromosome 1q43 and RYR3-FMN1-CKTSF1B1 (Gremlin) locus at human chromosome 15q13-q14 were paralogous regions (paralogons) within the human genome. This is the first report on comprehensive characterization of the human FMN2 gene.

Chronic myeloid leukemia is characterized by a t(9;22)(q34;q11.2) resulting in BCR/ABL1 fusion located on the derivative chromosome 22, also known as the Philadelphia chromosome. We present the first case, to our knowledge, of chronic myeloid leukemia with 2 cryptic insertional events resulting in BCR/ABL1 fusion on the derivative chromosome 9 and FNBP1/BCR fusion on the derivative chromosome 22. These insertional events were misinterpreted as a typical balanced BCR/ABL1 translocation by interphase fluorescence in situ hybridization studies and were cryptic by conventional chromosome analysis, resulting in a "normal" karyotype. Mate-pair sequencing, a novel next-generation sequencing technology that can detect and characterize structural variants with significantly higher resolution and precision compared with traditional cytogenetic methodologies, identified 2 insertional events and resolved the seemingly discrepant chromosome and fluorescence in situ hybridization results. This case demonstrates the complexities of genetic abnormalities unappreciable by traditional cytogenetic methodologies and highlights the clinical utility of mate-pair sequencing.
