Comparative Genomics of the RBR Family, Including the Parkinson's Disease–Related Gene Parkin and the Genes of the Ariadne Subfamily
2002
Genes of the RBR family are characterized by the RBR signature (two RING finger domains separated by an IBR/DRIL domain). The RBR family is widespread in eukaryotes, with numerous members in animals (mammals, Drosophila, Caenorhabditis) and plants (Arabidopsis). But yeasts, such as Saccharomyces cerevisiae or Schizosaccharomyces pombe, contain only two RBR genes. We determined the phylogenetic relationships and the most likely orthologs in different species of several family members for which functional data are available. These include: (1) parkin, whose mutations are involved in forms of familial Parkinson's disease; (2) the ariadne genes, recently characterized in Drosophila and mammals;…
A comparative evaluation between dermatoglyphic patterns and different terminal planes in primary dentition
2018
Background To assess the correlation between different dermatoglyphic patterns with the terminal planes in deciduous dentition. Material and methods 300 children who are 3-6 years old with complete primary dentition were recruited and the pattern of molar terminal plane was recorded in the proforma. Finger prints of the distal phalanges of these subjects were recorded using ink and roller method and were analysed for the finger print pattern by a forensic specialist. The pattern were classified based on classification given by Galton. The finger ridge counts were also measured. Results Ulnar loop pattern was the most predominant dermatoglyphic pattern. Absence of arch pattern in ring and li…
Evolution of chromatin-remodeling complexes: comparative genomics reveals the ancient origin of "novel" compensasome genes.
2003
Dosage compensation in Drosophila is mediated by a complex, called compensasome, com- posed of at least five proteins and two noncoding RNAs. Genes encoding compensasome proteins have been collectively named male-specific lethals or msls. Recent work showed that three of the Drosophila msls (msl-3, mof, and mle) have an ancient origin. In this study, I describe likely orthologues of the two re- maining msls, msl-1 and msl-2, in several inverte- brates and vertebrates. The MSL-2 protein is the only one found in Drosophila and vertebrate genomes that contains both a RING finger and a peculiar type of CXC domain, related to the one present in Enhancer of Zeste proteins. MSL-1 also contains two…
The yeast putative transcriptional repressor RGM1 is a proline-rich zinc finger protein.
1991
Abstract I have cloned a yeast gene, RGM1, which encodes a proline-rich zinc, finger protein. rgm1 mutants do not show any obvious phenotype but overexpression of RGM1 gene greatly impairs cell growth. The proline-rich region of RGM1 attached to a heterologous DNA binding domain is able to repress the expression of the target gene. RGM1 shares similar zinc finger motifs with the mammalian Egr (early growth response) proteins as well as proline-rich sequences with a high serine and threonine content, suggesting that RGM1 and Egr proteins could have functional similarities.
