The Recent De Novo Origin of Protein C-Termini
Protein-coding sequences can arise either from duplication and divergence of existing sequences, or de novo from noncoding DNA. Unfortunately, recently evolved de novo genes can be hard to distinguish from false positives, making their study difficult. Here, we study a more tractable version of the process of conversion of noncoding sequence into coding: the co-option of short segments of nonco...
متن کاملOn the parental origin of de novo mutation in man.
Studies tracing parental origins of human mutations by means of cytogenetic polymorphisms and RFLPs show that most trisomics arise out of maternal errors of segregation at the first meiotic division in oocytes. Temporal disturbance of meiotic progression seems likely to underly aneuploidy production in the female mouse, and this could equally be true in women, most especially as they approach t...
متن کاملDe-Novo Presentation of Histoid Leprosy on an Unusual Site
Histoid Leprosy (HL) is a rare variant of Lepromatous Leprosy, occurring in long-standing cases, mostly in a background of acquired drug resistance. Patients usually present with sudden onset multiple nodules and plaques, most often involving the skin and subcutaneous tissue of trunk and lower limbs. Here we report an unusual case of de novo (without any history of prior anti-leprotic therapy) ...
متن کاملDe Novo Origin of Human Protein-Coding Genes
The de novo origin of a new protein-coding gene from non-coding DNA is considered to be a very rare occurrence in genomes. Here we identify 60 new protein-coding genes that originated de novo on the human lineage since divergence from the chimpanzee. The functionality of these genes is supported by both transcriptional and proteomic evidence. RNA-seq data indicate that these genes have their hi...
متن کاملDe Novo Origin of Protein-Coding Genes in Murine Rodents
BACKGROUND New genes in eukaryotes are created through a variety of different mechanisms. De novo origin from non-coding DNA is a mechanism that has recently gained attention. So far, de novo genes have been described in a handful of organisms, with Drosophila being the most extensively studied. We searched for genes that have appeared de novo in the mouse and rat lineages. METHODOLOGY Using ...
