Cereblon-based small-molecule degraders rely on the sequential action of ubiquitin-conjugating enzymes UBE2G1 and UBE2D3 to assemble K48-linked polyubiquitin chains on cereblon neomorphic substrates, resulting in their proteasomal degradation.
In the retina, the receptive field surround preserves the spatial contrast sensitivity of the center in the face of naturalistic changes in local luminance.
Yeast RNA helicase Ded1 stimulates ribosome recruitment of structure-laden native mRNAs in a reconstituted system by interactions between domains in Ded1 and initiation factor eIF4G that stabilizes a Ded1-eIF4F complex.

Neurophysiological and behavioral approaches reveal how coordinated input from descending pathways shapes the tuning properties of electrosensory neurons in order to optimize coding of natural stimuli through temporal whitening.

While the basal ganglia have long been thought to mediate learning through dopamine-dependent striatal plasticity, their regulation of motor thalamus plays an unexpected and critical role in reinforcement.
Computational model reveals how the fast exchange of neurotransmitter receptors between synapses induces a competition leading to a transient form of heterosynaptic plasticity and shaping the induction of homosynaptic plasticity.

Unlike other taste modalities, the Drosophila taste system encodes salt taste combinatorially across multiple sensory neuron classes, which combine to produce behavioural valence and plasticity.
