Regulatory events

The first major federal regulatory event affecting natural gas pipelines was the Natural Gas Act of 1938, which gave the Federal Power Commission jurisdiction to regulate three areas (1) pipeline sales of gas purchased from producers and resold to local distribution companies in interstate commerce (2) transportation m interstate commerce and (3) the facilities used for such sales and such transportation. 

The physiological roles of the yeast (and their human homologues) alkaline ceramidases are yet to be established. Since these enzymes regulate a series of bioactive lipids such as ceramide, sphingosine, and sphingosine-1-P, we predict that they have an important role in cell regulatory events. 

Hardin It may not be important for the raw function of the oscillator. There may be enough post-transcriptional regulatory events there which can maintain function even without RNA cycling. For constant expression of all the core components Amita Sehgal has come the closest in that she constantly expressed tim and per, and the oscillator works you get some rhythmic animals. 

The first site-specific recombination system studied in vitro was that encoded by bacteriophage A. When A phage DNA enters an E. coli cell, a complex series of regulatory events commits the DNA to one of two fates. 

We focus on regulatory events that occur in development. First we discuss some of the classical studies of gene expression in the embryogenesis of sea urchins and amphibians and then turn to some of the developmental events in fruit flies, the best characterized developmental system.

Despite the fundamental importance of receptor-catalyzed G protein activation in cellular signaling, relatively little is known about this process as compared to the other regulatory events in the G protein cycle. Crystal structures of inactive rhodopsin and G protein heterotrimers provide the structural context for the meaningful interpretation of the results of the numerous biochemical and biophysical studies described in the preceding sections. Enough data has been accumulated to begin to develop rudimentary models of the receptor-G protein complex that meet some of...

Each of the three EF-hand structures solved from the spectrin family proteins exhibit unique structural and functional differences, even though all are fundamentally similar. The a-spectrin (nonerythroid) EF hands bind calcium and presumably perform some kind of regulatory role regarding the actin-binding function of spectrin (Trave et al., 1995). Due to the low calcium affinity, it is expected that calcium regulatory events involving spectrin would occur in areas of the cell that would experience a transient but significant fluctuation of calcium concentration (Buevich et al., 2004). It is possible that the calcium-bound form of...

Proteomics is complicated by the fact that the absolute quantification does not always reflect the molecular function of proteins, because protein activities are highly regulated post-translationally. Post-translational modifications modulate the function of proteins and thus directly impact their capacity to participate in cellular regulatory events (Cravatt and Sorensen 2000). Due to post-translational modifications, the numbers of proteins in human are estimated to be at least three times the amount of genes. Therefore, the elucidation of protein post-translational modifications is the most important justification for biochemical and structural relationships. Hence, these modifications need to be evaluated.
