In other cases, sequences outside of the WDR may confer a new functional specificity to the protein even as conserved protein interactions are maintained through the WDRs, potentially adapting basic cellular mechanisms to organism-specific processes.
Analyzing genes harboring hyper-DMRs in their respective promoter regions by Gene Ontology (GO) analysis (Biological process, level 5) revealed an enrichment of basic cellular mechanisms, such as RNA metabolism, regulation of transcription, cellular biosynthesis, nucleobase, nucleoside, nucleotide and nucleic acid metabolism, macromolecule biosynthesis and transferase activity (FDR, p < 0.05).
Where conservation was found, it often extended across all of these organisms, suggesting that many of these proteins are components of basic cellular mechanisms.
Our understanding of basic cellular mechanisms regulating chondrocyte responses to inflammatory cytokines has been inferred from numerous studies in vitro with cultures of cartilage fragments or isolated chondrocytes and is supported by studies in experimental models of inflammatory arthritis such as collagen-induced arthritis (CIA) and antigen-induced arthritis (AIA) in mice.
As expected, these included genes for mobility of DNA fragments but, interestingly, also genes associated with basic cellular mechanisms such as translation and regulation of transcription and transduction.
Particular attention will be focused on the role of insulin resistance and recent advances in our understanding of the basic cellular mechanisms linking obesity and insulin resistance.
Because they are involved in the regulation of several basic cellular mechanisms (signal transduction pathways, protein trafficking, DNA damage, etc), HECT proteins have attracted a considerable attention and interest in them is growing since they have been found to be involved in several human diseases (reviewed in [ 4, 7- 9]).
Where conservation was found, it often extended across all of these organisms, suggesting that many of these proteins are linked to basic cellular mechanisms.
The three researchers independently unraveled basic cellular mechanisms several decades ago in Schekman's case, almost 40 years ago.
