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.
