As a base for human transcriptome and functional genomics, we created the "full-length long Japan" (FLJ) collection of sequenced human cDNAs. We determined the entire sequence of 21,243 selected clones and found that 14,490 cDNAs (10,897 clusters) were unique to the FLJ collection. About half of them (5,416) seemed to be protein-coding. Of those, 1,999(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)
HUGE is a database for human large proteins newly identified by Kazusa cDNA project, which aims to predict protein primary structures from sequences of human large cDNAs (>4 kb). In particular, cDNA clones capable of coding for large proteins (>50 kDa) are current targets of the project. More than 700 sequences of human cDNAs (average size, 5.1 kb) have(More)
We have been developing a HUGE database to summarize results from the sequence analysis of human novel large (>4 kb) cDNAs identified in the Kazusa cDNA sequencing project, systematically designated KIAA plus a four-digit number. HUGE currently contains nearly 2000 gene/protein characteristic tables harboring the results of the computer-assisted analysis of(More)
We here modified a previously reported method for the construction of cDNA libraries by employing an in vitro recombination reaction to make it more suitable for comprehensive cDNA analysis. For the evaluation of the modified method, sets of size-selected cDNA libraries of four different mouse tissues and human brain were constructed and characterized.(More)
In eukaryotic cells, post-translational histone modifications have an important role in gene regulation. Starting with early work on histone acetylation, a variety of residue-specific modifications have now been linked to RNA polymerase II (RNAP2) activity, but it remains unclear if these markers are active regulators of transcription or just passive(More)
Recent studies have suggested that peripheral tissues in mammals have an autonomous circadian oscillator driven by negative feedback loops consisting of periodical expression of clock genes. In the present study we investigated the mechanism that regulates circadian rhythms in mammalian peripheral tissues, and observed developmental aspects in circadian(More)
Recent advances suggest that the molecular components of the circadian clock generate a self-sustaining transcriptional-translational feedback loop with a period of approx. 24 h. The precise expression profiles of human clock genes and their products have not been elucidated. We cloned human clock genes, including per1, per2, per3, cry2 and clock, and(More)
Smurf1, a member of HECT-type E3 ubiquitin ligases, regulates cell polarity and protrusive activity by inducing ubiquitination and subsequent proteasomal degradation of the small GTPase RhoA. We report here that hPEM-2, a guanine nucleotide exchange factor for the small GTPase Cdc42, is a novel target of Smurf1. Pulse-chase labeling and a ubiquitination(More)
The SMARCAD1/KIAA1122 protein is structurally classified into the SWI2/SNF2 superfamily of DNA-dependent ATPases that are catalytic subunits of chromatin-remodeling complexes. Although the importance of other members of the SWR1-like subfamily in chromatin remodeling (EP400, INOC1, and SRCAP) has already been elucidated, the biological function of(More)
