Protein Transport into Chloroplasts
Annual Review of Plant Biology, 2010Most proteins in chloroplasts are encoded by the nuclear genome and synthesized as precursors with N-terminal targeting signals called transit peptides. Novel machinery has evolved to specifically import these proteins from the cytosol into chloroplasts.

Thyroid Hormone Transport Proteins
Clinics in Laboratory Medicine, 1993TBG, TTR, and albumin are quantitatively the most important thyroid hormone binding proteins in humans. Only a minute fraction of T3 and T4 circulates unbound, but it is this free hormone that is metabolically active at the tissue level, and, therefore, responsible for thyroid status. Inherited or acquired variations in the concentration or affinity of

Motor proteins transporting cargos
The European Physical Journal E, 2005Processive motor proteins such as kinesin and myosin-V are enzymes that use the energy of ATP hydrolysis to travel along polar cytoskeletal filaments. One of the functions of these proteins is the transport of vesicles and protein complexes that are linked to the light chains of the motors. Modeling the light chain by a linear elastic spring, and using

Nuclear Protein Transport Pathways
Nephron Experimental Nephrology, 1999Nuclear proteins like transcription factors and ribosomal proteins are synthesized in the cytoplasm and have to be transported into the nucleus to fulfill their functions. The transport of proteins >20–60 kD through the nuclear pore complex (NPC) into the nucleus is an active, energy-requiring process.

Nucleocytoplasmic transport of proteins
Biochemistry (Moscow), 2007In eukaryotic cells, the movement of macromolecules between the nucleus and cytoplasm occurs through the nuclear pore complex (NPC)--a large protein complex spanning the nuclear envelope. The nuclear transport of proteins is usually mediated by a family of transport receptors known as karyopherins.

The relative constancy of the internal environment of the cell is maintained by a variety of transport systems which are located within the membrane. These transport systems serve to regulate the entrance and exit of various solutes concerned with the metabolic activity of the cell.

Glycosylation and protein transport
Essays in Biochemistry, 2000Transport along the secretory pathway is largely signal-mediated. Proteins in the secretory pathway can be covalently modified with various carbohydrate structures, most commonly O-glycans, N-glycans and/or proteoglycans. Carbohydrate modifications can change the physical properties of proteins or can function as specific recognition epitopes ...

Electronic Transport via Proteins
Advanced Materials, 2014A central vision in molecular electronics is the creation of devices with functional molecular components that may provide unique properties. Proteins are attractive candidates for this purpose, as they have specific physical (optical, electrical) and chemical (selective binding, self‐assembly) functions and offer a myriad of possibilities for (bio ...

Glucose transporter protein syndromes
2002Publisher Summary The disturbances of carbohydrate homeostasis have interested clinicians and scientists since the recognition of diabetes mellitus. A parallel line of study emerged in the study of patients with recurrent or chronic hypoglycemic syndromes.
