Coarse-grained modeling reveals a new mechanism for multispanning membrane protein topogenesis, in which misintegrated configurations of the proteins undergo post-translational annealing to reach final, fully integrated multispanning topologies.
The insect dopaminergic system serves an important function in the regulation of ontogenesis and early development, contributing to the evolutionary processes that limit the ecological niche of Drosophila sechellia.
In nematode worms, NSUN-1 methylates ribosomal RNA and influences phenotypes related to aging, stress resistance, germ line development, and cuticle integrity by regulating translation of specific mRNAs.
Developing oocytes lacking Sphk2 sense high sphingosine levels and transcriptionally activate expression of the gene encoding Cers2b, to mediate a salvage pathway to reduce potentially toxic sphingosine.
An insulin-Myc feed-forward loop triggered by transient JNK boosts transcription of genes essential for mitochondrial respiration and biogenesis during early oogenesis to support massive mtDNA replication and inheritance in Drosophila.
