Two kinds of cDNAs that are highly homologous to mammalian MBD2 and MBD3 cDNAs were cloned from ovary of the starfish Asterina pectinifera. They are splicing variants and designated sMBD2/3a and sMBD2/3b cDNAs. sMBD2/3a cDNA spans 1378 bp and consists of a 48-bp upstream untranslated region, a 807-bp open reading frame encoding sMBD2/3a, and a 523-bp downstream untranslated region. sMBD2/3a and sMBD2/3b...
The methyl-CpG binding domain protein MBD3 has been shown to be essential for embryonic development and differentiation, and to act by suppressing gene expression through the recruitment of co-repressor complexes. We have recently shown that MBD3 is also involved in maintaining the demethylated and active state of rRNA genes, and that depletion of MBD3 results in hypermethylation of rRNA promoters...
Mitochondrial DNA is well characterized in vertebrates and insects and represents a prime target for phylogenetic and population genetic analyses. In particular the highly variable control region, responsible for regulation of replication and transcription, has been studied by molecular biologists and geneticists alike. However, we lack basic information on the structure and molecular evolution of...
The A20/AN1-type zinc finger protein family is conserved in animals and plants. Using human AWP1 protein as a query, we identified twelve A20/AN1-type zinc finger proteins in japonica rice. Most of these genes were constitutively expressed in leaves, roots, culms and spikes. Through microarray analysis, it was found that four genes (ZFP177, ZFP181, ZFP176, ZFP173), two genes (ZFP181 and ZFP176) and...
Plant hormone auxin elicits diverse responses in plant growth and development. Accumulated data indicate that the ubiquitin-mediated proteolytic pathway plays a crucial role in transducing auxin signaling. To gain more understanding of the molecular mechanisms underlying auxin action, we performed a comparative transcriptome analysis of auxin responsive genes between Arabidopsis Columbia ecotype and...
Copy number variants contribute extensively to inter-individual genomic differences, but little is known about their inter-population variability and diversity. In a previous study (Bosch et al., 2007; 16:2572–2582), we reported that the primate-specific gene family FAM90A, which accounts for as many as 25 members in the human reference assembly, has expanded the number of FAM90A clusters across the...
