The Tenth Symposium on Polar Science/Special session: [S] Future plan of Antarctic research: Towards phase X of the Japanese Antarctic Research Project (2022-2028) and beyond, Tue. 3 Dec. / Entrance Hall (1st floor) at National Institute of Polar Research (NIPR

cDNA cloning of a human brain finger protein, BFP/ZNF179, a member of the RING finger protein family.

The rat bfp/znf179 transcript for a member of the RING finger protein family, is expressed in brain and up-regulated in neural differentiation of P19 embryonic carcinoma cells. Here we report the full-length cDNA structure of human BFP/ZNF179 and its expression profile. The cDNA clone consists of 3082 nucleotides and encodes an open reading frame of a 632-amino acid protein that contains a RING finger domain at its N-terminus, and alanine-rich and glycine-rich domains at its C-terminus. Reverse transcriptase polymerase chain reaction analysis of various human tissues indicated that BFP/ZNF179 is predominantly expressed in brain

PKCnu, a new member of the protein kinase C family, composes a fourth subfamily with PKCmu.

Members of the protein kinase C (PKC) family of serine/threonine kinases are thought to play critical roles in the regulation of cellular differentiation and proliferation in many cell types. An additional member of the PKC family was identified through human expressed sequence tag (EST) database search and its full length cDNA was isolated. Sequence analysis revealed that the predicted translation product was composed of 890 amino acid residues and that the protein has 77.3% similarity to human PKC mu (PKCmu) and 77. 4% similarity to mouse PKD (the mouse homolog of PKCmu). We designated the new member as protein kinase C nu (PKCnu). The PKCnu messenger RNA was ubiquitously expressed in various tissues when analyzed by Northern blots and reverse transcriptase-coupled polymerase chain reaction (PCR) analyses. The chromosomal location of the gene was determined between markers WI-9798 and D2S177 on chromosome 2p21 region by PCR-based methods with both a human/rodent monochromosomal hybrid cell panel and a radiation hybrid mapping panel

Genomic structure of mouse and human genes for DNA-PKcs interacting protein (KIP).

DNA-dependent protein kinase (DNA-PK) is a nuclear protein serine/threonine kinase in a wide variety of vertebrate species and it has a role in the DNA repair and recombination process of lymphoid development. DNA-PK is composed of a large catalytic subunit (DNA-PKcs) and DNA-binding protein, Ku. Recently, the mouse and human DNA-PKcs interacting proteins (Kip/KIP) have been reported. In this report, we have determined the complete genomic structure of mouse and human Kip/KIP genes. The total length of mouse Kip gene and human KIP gene are approximately 5.7 kb and 3.6 kb in genomic DNAs, respectively. Both of genes consist of 7 exons

cDNA cloning, expression profile, and genomic structure of human and mouse RNF10/Rnf10 genes, encoding a novel RING finger protein.

RING finger (C3HC4-type zinc finger) is a variant zinc finger motif present in a new family of proteins including transcription regulators. A new member of the RING finger protein family was identified through a mouse expressed sequence tag (EST) database search, and its full-length cDNA was isolated from a mouse brain full length-enriched cDNA library. The gene was designated as Rnf10, for RING finger protein 10. The cDNA clone consists of 3110 nucleotides and encodes an open reading frame (ORF) of an 804-amino acid protein. A database search revealed that human KIAA0262 protein (accession number, D87451) has strong homology to mouse Rnf10. To confirm that mouse Rnf10 is the homolog or an isolog of human KIAA0262, a human RNF10 cDNA was cloned in our hands from a fetal brain cDNA pool. The newly isolated cDNA contained an ORF for 811 amino acids which had almost identical structure to mouse Rnf10 protein, indicating that the human ORF codes for RNF10 protein. This finding was also supported by comparative chromosome mapping in which both genes were localized in a conserved linkage homology region between mouse and human. Comparison of the RNF10 and KIAA0262 proteins revealed that both were transcribed from the same gene and that the longer RNF10 ORF would be the authentic form. The complete genomic organization of RNF10 was determined to consist of 17 exons spanning at least 40kb in the genome
