Since animal tissues are in general simpler to digest than plant tissues, the carnivore's dependence on a diet with a high proportion of meat has led to less-complex compartmentalization of the stomach and a decrease in the length and folding (and therefore surface area) of the intestine.
Translational regulation in the oocyte is a complex process involving multi-component RNA-binding complexes, compartmentalization of maternal RNAs and polyadenylation-induced translation (reviewed in 43, 44).
In terms of cell biology, their complex compartmentalization is of major interest, because several plasmas and genomes coexist in these organisms, which can be traced back to either a prokaryote or a eukaryote [ 27].
This organization highlights the complexity and compartmentalization of the heart.
Association with β-arrestin also influences compartmentalization of complexes in the cellular milieu including internalization, recycling and degradation through their ability to bind other structural and regulatory proteins (Moore et al., 2006).
The evidences till now available have clarified some aspects of the very complex problem of cell signal integration, differential activation of signaling modules and intracellular compartmentalization of active complex that constitutes the inner causes of cellular response to changes in extracellular environment.
Compartmentalization of replication complexes likely accounts for the observation that many functions of nonstructural proteins cannot be complemented in trans (Novak and Kirkegaard, 1994; Ansardi et al., 1996).
To explore the cellular compartmentalization of Wip1/BAX complexes, co-immunoprecipitation experiments using anti-BAX antibodies were performed with nuclear and cytoplasmic fractions of LNCaP cells after 6 h of γ-irradiation.
Finally, it is now well documented that endosomes, in addition to controlling the recycling or degradation of receptors, have been also evolutionarily exploited as subcellular platforms for the assembly and compartmentalization of signaling complexes in space and time.
Because of the intricate buildup and compartmentalization of the diatoms complex plastid (four envelope membranes), an efficient flux of CO2 for acquisition and fixation of inorganic carbon by RuBisCO might be much more challenging than in organisms with primary plastids.
