Together, these data reveal no effect of Ro 25-6981, and only a small effect of ifenprodil on t-LTD or t-LTP in P11 15 mice, suggesting that GluN2B subunit might not be essential for timing-dependent plasticity at layer 4-to-layer 2/3 synapses.
Follow the package directions for timing.
Aortic enlargement monitoring is essential for surgical timing and for operative design.
Additionally, some SAC components are essential for correct timing of prometaphase.
However, on a structural level there is significant debate over which conformational changes are essential for the timing of the reaction.
Regulation of phosphorylation of APC subunits and Cdc20 is essential for the timing of APC activation during mitotic progression (Kramer et al., 2000); APC-Cdc20 is also modulated by its inhibitor proteins (Luo et al., 2000; Madgwick et al., 2006).
Downregulation of the abrupt (ab) gene encoding a BTB-zinc finger transcription factor that regulates the specificity of neuron-muscle connections by let-7 is essential for the timing of neuromusculature remodelling (Hu et al, 1995; Caygill and Johnston, 2008).
In the auditory system, for example, it is essential for the timing of signals to be preserved as they are sent from the ear to the brain, and this places special demands on the synapses in this part of the nervous system.
The neurons of the medial superior olive (MSO), an SOC nucleus, display a precise geometric organization essential for detection of timing differences between the two ears.
The core circadian gene cryptochrome 2 (CRY2) is essential for proper circadian timing, and is a key component of the negative arm of the circadian feedback loop.
All three of these G- and T-rich motifs are also related to a motif (CNWWGTGGGGG, where N represents any nucleotide and W represents A or T) observed by Hayano et al. to be enriched in sites that bind Rif1, a protein essential for normal replication timing in fission yeast.
