Several tumor suppressor genes are located within human chromosome 11q23 region. We have cloned and characterized MFRP and RNF26 genes at 11q23.3. We also identified and characterized KIAA1735/MTHDIX gene at 11q23.1 and CLDN24 gene at 11q23.2 by using bioinformatics. Here, a novel human gene corresponding to a 5'-truncated FLJ20535 cDNA was identified. FLJ20535 corresponded to nucleotide position 55-2255 of FLJ13859, and nucleotide position 52-2169 of FLJ13859 was the coding region. Because of tetratricopeptide repeat (TPR) and armadillo repeat (ARM) domains within its gene product, the novel human gene was designated TPARM. Mouse E330017O07Rik cDNA was derived from mouse Tparm gene. Human TPARM (705 aa) and mouse Tparm (704 aa), showing 75.4% total-amino-acid identity, consist of TPR domain and three ARM domains. TPR domain of TPARM was most homologous to that of SMAP1, while ARM1-ARM3 domains of TPARM were most homologous to ARM7-ARM9 domains of CTNNB1 (also known as beta-catenin). TPARM might be implicated in the WNT-beta-catenin signaling pathway. TPARM mRNA was expressed in testis, prostate, lung, germinal center B-cells, and also in neuroblastoma, teratocarcinoma, colon cancer, and gastric cancer. Human TPARM gene was found to consist of 22 exons. TPARM gene, located between NCAM1 and DRD2 genes, was mapped to human chromosome 11q23.2. TPARM as well as NCAM1 and DRD2 were predicted to be candidate tumor suppressor genes within the commonly deleted region of malignant melanoma on 11q23.1-q23.2 (between microsatellite markers D11S1347 and D11S4122).

Tumor suppressor genes of neuroblastoma are located at human chromosome 1p36, 4p16, 11q23.3, and 14q32. We have previously cloned and characterized MFRP and RNF26 genes at 11q23.3. Here, we searched for genes within the 1p36.31-p36.23 commonly deleted region between microsatellite markers D1S2731 and D1S2666 by using bioinformatics. D1S2731 was located within FLJ10737 gene, consisting of 16 exons. D1S2666 was located within CAMTA1 gene, consisting of 23 exons. FLJ10737 and CAMTA1 genes were located in the head-to-head manner with an interval of about 83 kb. Exons 1-10 of FLJ10737 gene as well as exons 1-5 of CAMTA1 gene were located within the 1p36.31-p36.23 commonly deleted region. FLJ10737 (559 aa) was found to consist of the DnaJ domain, bipartite nuclear localization signal (NLS), FADH domain, and FEMCA domain. Mouse E030019A03, zebrafish MGC55845, Drosophila CG8531 and Arabidopsis At2g35720 were homologs of human FLJ10737. FADH domain was conserved among vertebrate FLJ10737 orthologs as well as human AD-015, mouse Histocompatibility 47, and rat Ratsg2. KIAA0833 was the representative human CAMTA1 cDNA. Nucleotide sequence of mouse Camta1 cDNA was determined in silico by assembling nucleotide sequences of BY733411, BU610694 ESTs and AK122383 cDNA. Human CAMTA1 (1673 aa) and mouse Camta1 (1682 aa) showed 94.1% total-amino-acid identity. CAMTA1 was a Calmodulin-binding transcription activator (CAMTA) family protein, consisting of CG-1 domain, TIG domain, ankyrin repeats, and IQ motifs. FLJ10737 and CAMTA1 genes on 1p36.31-p36.23 are candidate tumor suppressor genes of neuroblastoma.

ARCN1, KIAA0638, TREH, DDX6, BLR1, BCL9L, UPK2, DLNB13, DLNB14, RPS25, SBDN, G6PT1, HYOU1, VPS11, HMBS, H2AFX, DPAGT1, KIAA0285, MIZF, ABCG4, NOD9, PDZK2, CBL, MCAM, RNF26, C1QTNF5, MFRP, USP2, THY1, and PVRL1 genes are located within the commonly deleted region of neuroblastoma at human chromosome 11q23.3. Here, we characterized the KIAA0638 gene within the 11q23.3 region by using bioinformatics. Because human KIAA0638 gene was homologous to human LL5B gene encoding LL5beta protein, KIAA0638 was designated LL5A gene encoding LL5alpha protein. LL5A isoform 1 (FLJ00141 type) consists of exons 1-12, 14-21 and 23, while LL5A isoform 2 (KIAA0638 type) consists of exon 1-23. LL5A isoform 1 was the major transcript among LL5A isoforms generated due to alternative splicing. Nucleotide sequence of mouse Ll5a cDNA was determined by assembling CB522359 EST and 5'-truncated mKIAA0638 cDNA. Human LL5alpha isoform 2 showed 94.4 and 35.9% total-amino-acid identity with mouse Ll5alpha and human LL5beta, respectively. LL5alpha proteins consist of Forkhead associated (FHA) domain, bipartite nuclear localization signal (NLS), Chromosome segregation ATPases (SMC) domain, and Pleckstrin homology (PH) domain. LL5alpha proteins were homologous to PtdIns(3,4,5)P3 sensor protein LL5beta in the SMC and PH domains, and were also homologous to KIF1A, KIF1B, KIF13A, KIF13B, KIF14, and SNX23 proteins in the FHA domain. LL5alpha protein might be a transducer of PtdIns(3,4,5)P3 levels to the intracellular trafficking system.

MLL gene at human chromosome 11q23.3 is frequently rearranged or amplified in hematological malignancies, while PHLDB1, BCL9L, FOXN5 (FOXR1), RNF26, and MFRP genes linked to MLL gene are deleted in neuroblastoma. Here, we characterized the TMEM24 gene family by using bioinformatics. KIAA0285 gene within the 11q23.3 commonly deleted region of neuroblastoma was designated TMEM24, because KIAA0285 gene product was a 707-aa (or 706-aa) protein with N-terminal short cytoplasmic region, single transmembrane domain, and C-terminal large extracellular region. C21orf25 (NM_199050.1) encoded an N-terminally truncated 541-aa protein homologous to TMEM24. Complete coding sequence of C21orf25 was determined by assembling exons 1 and 2 within human genome sequence AP001745 and NM_199050.1 cDNA. Full-length C21orf25 encoded a 696-aa TMEM24-related protein with similar membrane topology. Exon-intron structure was conserved between TMEM24 and C21orf25 genes. TMEM24-ABCG4 locus at human chromosome 11q23.3 and C21orf25-ABCG1 locus at human chromosome 21q22.3 were paralogous regions (paralogons) with insertions of other genes due to recombination during evolution. Mouse 1300006O23 (BC060156.1) and 5830404H04 (NM_174847.1) cDNAs were derived from orthologs of human TMEM24 and C21orf25 genes, respectively. TMEM24 homologous domains (TM24H1 and TM24H2) were identified as novel domains conserved among TMEM24, C21orf25, 1300006O23, and 5830404H04. Human TMEM24, C21orf25 and their mouse homologs were type II transmembrane proteins with extracellular TM24H1 and TM24H2 domains. This is the first report on identification and characterization of the TMEM24 family.
