The B cell receptors of naïve B cells need higher levels of mechanical force to be fully activated than those of memory B cells.

The kinase that controls maternal mRNA translation is regulated by phosphorylation of its activating subunit to restrict kinase activity to the developmental window between meiosis completion and early embryogenesis.

In Aves, the first wave of transcription is derived exclusively from the maternal genome.

Conformational changes occur within extracellular domain of BCR upon antigen engagement, and these conformational changes are related with the strength of BCR activation and are distinct in IgM- and IgG-BCR.

In fruit flies, maternally deposited RNA-binding proteins are removed during the maternal-to-zygotic transition via a mechanism of translational upregulation of Kondo, the key E2 enzyme, at egg activation.

The neural circuit that regulates egg-laying behavior in nematode worms is activated by egg production, coupled to the circuit that generates movement, and inhibited by sensory feedback from egg release.

The elongation rate of RNA Polymerase II varies greatly between and along genes, as this enzyme accelerates from stable pausing to rapid elongation within genes, and is influenced by CG-content, exons and chromatin.

Odor cues in sleep evoke content-specific signatures of neural reactivation in visual and prefrontal brain areas that predict subsequent memory performance in the wake state.

The molecular identity of the temperature-sensitive ion channel of human sperm that ensures depolarization is TRPV4.

Two protein kinases are required to activate auxin efflux transporters from plants.
