The transcription of major histocompatibility complex class II (MHC II) genes is dependent on the co-activator protein class II trans-activator (CIITA). We have recently identified a protein known as zinc finger X-linked duplicated family m...

Plasma prekallikrein (PPK) is synthesised in hepatocytes and secreted into the blood, where it participates in the surface-dependent activation of blood coagulation, fibrinolysis, kinin generation and inflammation. Recently we demonstrated ...

The majority of cellular proteins are degraded by proteasomes within the ubiquitin-proteasome ATP-dependent degradation pathway. Products of proteasomal activity are short peptides that are further hydrolysed by proteases to single amino ac...

Genomic variations represent the molecular basis of the biodiversity of living organisms on which selection operates to generate evolution. In eukaryotes, genomic variability can be experienced in both nuclear and organellar, i.e. mitochond...

Plastids are derived from free-living cyanobacteria that were engulfed by eukaryotic host cells through the process of endosymbiosis and, like their cyanobacterial ancestors, divide by binary fission. Over the last decade the continued iden...

Chloroplasts gather in areas irradiated with weak light to maximize photosynthesis (the accumulation response). They move away from areas irradiated with strong light to minimize damage of the photosynthetic apparatus (the avoidance respons...

Mitochondria are amazingly dynamic organelles. They continuously move along cytoskeletal tracks and frequently fuse and divide. These processes are important for maintenance of mitochondrial functions, for inheritance of the organelles upon...

The thylakoid membrane of chloroplasts contains the major photosynthetic complexes, which consist of several either nuclear or chloroplast encoded subunits. The biogenesis of these thylakoid membrane complexes requires coordinated transport...

Many algal groups evolved by engulfment and intracellular reduction of a eukaryotic phototroph within a heterotrophic cell. Via this process, so-called secondary plastids evolved, surrounded by three or four membranes. In these organisms mo...

Mitochondria are ubiquitous organelles that play an essential role in energy conversion and biosynthetic pathways in eukaryotic cells. Most mitochondrial proteins must be imported from the cytosol and sorted into one of the four mitochondri...
