The MyD118 (Gadd45�) protein is a member of a family of structurally related proteins, including Gadd45 (Gadd45a) and CR6 (Gadd45?), that have critical roles in regulating growth arrest and apoptosis. The MyD118 and other members of its family display distinct patterns of expression in response to stimuli that induce differentiation, growth arrest, or apoptosis. Species-blot analysis showed that MyD118 is an evolutionarily conserved gene, and comparative sequence analysis showed that MyD118 has a gene structure similar to that of other members of its gene family. Comparison of putative transcription factor-binding sites found in sequences of this gene family provides evidence that p53 is involved in regulating the expression of MyD118 and that NF-?B may play a role in differential expression of MyD118 and Gadd45(Gadd45a). Fluorescence in situ hybridization localized the MyD118 gene to mouse chromosome band 10B5.3, correcting a previous assignment to mouse chromosome 9.

    Assigning functions to proteins of unknown function is of considerable interest to the proteomic researchers as the genes encoding them are conserved over various species. Here, we describe HypoDB, a database of hypothetical genes and proteins in six eukaryotes. The database was collected and...

    A common assumption in comparative genomics is that orthologous genes share greater functional similarity than do paralogous genes (the ''ortholog conjecture''). Many methods used to computationally predict protein function are based on this assumption, even though it is largely untested. Here...

    The halophilic archaeon Haloferax volcanii has a multireplicon genome, consisting of a main chromosome, three secondary chromosomes, and a plasmid. Genes for the initiator protein Cdc6/Orc1, which are commonly located adjacent to archaeal origins of DNA replication, are found on all replicons...

    Background: Cercarial elastase is the major invasive larval protease in Schistosoma mansoni, a parasitic blood fluke, and is essential for host skin invasion. Genome sequence analysis reveals a greatly expanded family of cercarial elastase gene isoforms in Schistosoma mansoni. This expansion...

    Nuclear localization influences the expression of certain genes. Chromosomal rearrangements can reposition genes in the nucleus and thus could impact the expression of genes far from chromosomal breakpoints. However, the extent to which chromosomal rearrangements influence nuclear organization...
