Genetic lesions that compromise the ribosome P-stalk implicate direct signalling from the ribosome to the translation initiation factor eIF2 kinase GCN2 in the cellular response to amino acid starvation.

Phylogenetic analyses demonstrate an evolutionary trade-off between the amount of harm inflicted by a broad host-range virus and how effectively the virus positions itself within plants to enable onward transmission.
Calreticulin, beyond its known role as a chaperone, also serves as an endoplasmic reticulum repressor of ATF6⍺, selectively regulating one arm of the unfolded protein response.
New P-glycoprotein structures reveal a substrate translocation mechanism and pathway across lipid bilayers that challenges ATP-binding cassette transporter norms.

Contrary to the generally accepted model, condensin maintains proper gene expression by promoting the accurate segregation of chromosomes and the partitioning of the RNA-exosome throughout mitosis, instead of directly regulating transcription.
An analysis of vestibular projection neurons lacking their motor neuron partners resolves outstanding controversies for whether and how motor neurons shape vestibulo-ocular reflex circuit assembly.
