Individual neurons can adjust the strength of their synapses by using spontaneous calcium influx through NMDA receptors to trigger the release of additional calcium from intracellular stores, which can in turn be used to regulate protein synthesis.
As mice learn to associate events separated in time, neurons within the CA1 region of the hippocampus progressively reorganize their firing patterns, leading to a relay of cellular activity that bridges the two events.
During CRISPR adaptation, Cas4 forms a ternary complex with the Cas1-Cas2 spacer integration complex, an interaction that coordinates substrate hand-off following precise, PAM-dependent prespacer processing prior to integration.
La-related protein 1 specifically and directly binds the 5' cap and first nucleotide of mRNAs encoding ribosomal proteins and translation factors, inhibiting the assembly of translation initiation factors on these messages and therefore their translation.
C-terminus mediated inhibition is one emerging modality of intervention for L-type Ca2+ channels, which coordinate multiple motifs to acutely tune Ca2+ current and Ca2+ influx down to the lower limits preset by end-stage Ca2+-dependent inactivation.
