A cDNA library prepared from the mouse osteoblastic cell line MC3T3-E1 was screened for the presence of specifically expressed genes by employing a combined subtraction hybridization/differential screening approach. A cDNA was identified and sequenced which encodes a protein designated osteoblast-specific factor 2 (OSF-2) comprising 811 amino acids. OSF-2(More)
To extend our cDNA project for accumulating basic information on unidentified human genes, we newly determined the sequences of 100 cDNA clones from a set of size-fractionated human adult and fetal brain cDNA libraries, and predicted the coding sequences of the corresponding genes, named KIAA1019 to KIAA1118. The sequencing of these clones revealed that the(More)
The ORF sll1468 of Synechocystis sp. PCC6803 was identified as a gene for beta-carotene hydroxylase by functional complementation in a beta-carotene-producing Escherichia coli. The gene product of ORF sll1468 added hydroxyl groups to the beta-ionone rings of beta-carotene (beta, beta-carotene) to form zeaxanthin (beta, beta-carotene-3,3'-diol). This newly(More)
In our series of human cDNA projects for accumulating sequence information on the coding sequences of unidentified genes, we herein present the entire sequences of 100 cDNA clones of unidentified genes, named KIAA1544 to KIAA1643, from two sets of size-fractionated human adult and fetal brain cDNA libraries. The average sizes of the inserts and(More)
The human genome sequence defines our inherent biological potential; the realization of the biology encoded therein requires knowledge of the function of each gene. Currently, our knowledge in this area is still limited. Several lines of investigation have been used to elucidate the structure and function of the genes in the human genome. Even so, gene(More)
CLOCK is a positive component of a transcription/translation-based negative feedback loop of the central circadian oscillator in the suprachiasmatic nucleus in mammals. To examine CLOCK-regulated circadian transcription in peripheral tissues, we performed microarray analyses using liver RNA isolated from Clock mutant mice. We also compared expression(More)
The nucleotide sequences of the eight different influenza A virus segments (genes) were compared among 14 different subtypes. These comparisons demonstrate the presence of molecular clocks in the viral genes; they accumulated both silent and amino acid-changing substitutions at approximately constant rates with respect to time during evolution. In addition,(More)
In order to obtain information on the coding sequences of unidentified human genes, we newly determined the sequences of 100 cDNA clones of unknown human genes, which we named KIAA1193 to KIAA1292, from two sets of size-fractionated human adult and fetal brain cDNA libraries. The results of our particular strategy to select cDNA clones which have the(More)
Using the differential hybridization screening method between osteoblastic and fibroblastic cells, a cDNA clone coding for an osteoblast specific protein, named OSF-1, consisting of 168 amino acid residues including a possible 32 amino acid long leader sequence, was isolated from murine osteoblastic cell line MC3T3-E1. The OSF-1 gene was shown by Northern(More)
We identified a novel gene, kf-1, highly expressed in the normal cerebellum but not in the cerebral cortex, the expression of which could have been augmented in the cerebral cortex of a sporadic Alzheimer's disease patient. We cloned human and mouse entire kf-1 cDNAs encoding conserved 79 kDa proteins containing a zinc-binding RING-H2 finger motif at the(More)
