Although eIF2A is thought to be a translation initiation factor, loss of eIF2A has no effect on cellular mRNA translation in either unstressed or stressed conditions.
The jellyfish embryonic body axis is globally coordinated by conserved planar cell polarity (PCP) mechanisms and oriented by localised Wnt3 in two steps, highlighting PCP’s role in animal axis evolution.
A comparison of how two nematode species sense salts highlights how evolution can find different ways to establish asymmetry in small nervous systems to optimize the processing of chemosensory cues.
