Most organisms use different mechanisms of translation termination for the three types of stop codons, i.e. UAA, UAG, and UGA [1]. Using the GenBank database, we have conducted comprehensive computer analyses of translation termination sites in order to find the difference of consensus sequence patterns around each type of stop codons. We also systematically analyzed the preference of stop codo...

BACKGROUND Precision medicine is an emerging approach to disease treatment and prevention that takes into account individual variability in the environment, lifestyle, and genetic makeup of patients. Patient-specific human induced pluripotent stem cells hold promise to transform precision medicine into real-life clinical practice. Lamin A/C (LMNA)-related cardiomyopathy is the most common inher...

Species-specific differences in genes encoding type II GnRH receptor indicate that a functional hepta-helical receptor is produced in monkeys but not in rodents, cows, chimpanzees, or humans. To further investigate the extent of evolutionary differences, we sequenced the type II GnRH receptor gene from wild-type Soay sheep. The gene was isolated by long-distance PCR using primers to PEX11beta a...

Recessive congenital methemoglobinemia (RCM) due to NADH-cytochrome b5 reductase (cytb5r) deficiency leads to two different types of diseases. In the type I form, cyanosis is the only symptom, and the soluble enzyme is defective in red blood cells. In the type II form, cyanosis is associated with severe mental retardation and neurologic impairment; the enzymatic defect is systemic, involving bo...

UNLABELLED Strains of Rickettsia rickettsii, the causative agent of Rocky Mountain spotted fever (RMSF), differ dramatically in virulence despite >99% genetic homology. Spotted fever group (SFG) rickettsiae produce two immunodominant outer membrane proteins, rickettsial OmpA (rOmpA) and rOmpB, which are conserved throughout the SFG and thought to be fundamental to pathogenesis. rOmpA is present...

Until now the most efficient solution to align nucleotide sequences containing open reading frames was to use indirect procedures that align amino acid translation before reporting the inferred gap positions at the codon level. There are two important pitfalls with this approach. Firstly, any premature stop codon impedes using such a strategy. Secondly, each sequence is translated with the same...

Point mutations underlie many genetic diseases. In this regard, while programmable DNA nucleases have been used to repair mutations, their use for gene therapy poses multiple challenges: one, efficiency of homologous recombination is typically low in cells; two, an active nuclease presents a risk of introducing permanent off-target mutations; and three, prevalent programmable nucleases typicall...

Legume plants form nitrogen-fixing nodules on their roots in symbiosis with soil bacteria rhizobia. The number of symbiotic is controlled by a host plant via systemic mechanism known as autoregulation nodulation (AON). key players AON are the CLE peptides which produced root response to rhizobia inoculation and transported xylem shoot. In shoot, recognized CLV1-like receptor kinase, results sub...
