much to know about proteolysis: intricate proteolytic machineries compromise essential cellular functions.proteolysis has traditionally been considered as a radical way to terminate the function of a protein. however, protein destruction also is the starting point for many processes as they can only occur when the way has been cleared for the action of other proteins. protein destruction can occur virtually in all compartments and organelles of the cell, associated with cell membranes or large protein complexes, it determines subcellular partitioning, association with positive or negative regulators ...200818793136
genetic structuring and migration patterns of atlantic bigeye tuna, thunnus obesus (lowe, 1839).large pelagic fishes are generally thought to have little population genetic structuring based on their cosmopolitan distribution, large population sizes and high dispersal capacities. however, gene flow can be influenced by ecological (e.g. homing behaviour) and physical (e.g. present-day ocean currents, past changes in sea temperature and levels) factors. in this regard, atlantic bigeye tuna shows an interesting genetic structuring pattern with two highly divergent mitochondrial clades (clades ...200818798987
noradrenergic deficits alter processing of communication signals in female songbirds.during acoustic communication, animals must attend to sounds from a particular source while simultaneously rejecting intrusion from other sources. one possible candidate mechanism for this process is the noradrenergic system. noradrenaline is a neuromodulator that tunes sensory processing systems and regulates attention. we examined whether pharmacological degradation of the noradrenergic system using n-(2-chloroethyl)-n-2-bromobenzyl-amine hydrochloride (dsp-4) modifies processing of species-ty ...200818815444
