Membrane Transport Proteins

1974
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, 2000
Transport 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, 2014
A 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

2002
Publisher 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.

Human Calcium Transport Protein CaT1

Biochemical and Biophysical Research Communications, 2000
Transcellular calcium transport occurs in many epithelial tissues including intestine, kidney, and placenta. We identified the human ortholog (hCaT1) of a recently cloned rat calcium transport protein, CaT1, that mediates intestinal calcium uptake. hCaT1 messenger RNA is present in the gastrointestinal tract, including esophagus, stomach, duodenum ...

Fatty acid transport proteins

Current Opinion in Lipidology, 2007
Fatty acid transport proteins are a family of proteins involved in fatty acid uptake and activation. This review summarizes recent progress in elucidating the function of fatty acid transport proteins.Recent experiments clearly establish FATP1 as a regulated fatty acid transporter in both adipose tissue and muscle with important roles in energy ...

ABA Transport by ABCG Transporter Proteins

2014
The superfamily of ATP-binding cassette (ABC) transporters is one of the most abundant protein families in nature. These transporters are broadly conserved from prokaryotes to higher eukaryotes, and most of them transport various metabolites and signalling molecules in an ATP-dependent manner. Plant genomes in particular have large ABC families of more

Membrane transport proteins: not just for transport anymore

American Journal of Physiology-Renal Physiology, 2006
digitalis glucosides have been used for their cardiotonic properties for several centuries. It was not until the 1950s that the molecular target of these compounds was identified as the Na-K-ATPase.

PROTEINS OF AXONAL TRANSPORT: INTERACTION OF RAPIDLY TRANSPORTED PROTEINS WITH LECTINS

Journal of Neurochemistry, 1979
Abstract—Rapidly transported fucose‐labelled glycoproteins from the optic system of the rabbit were solubilised with the non‐ionic detergent Berol 172.The major labelled components were bound to wheat germ agglutinin or Concanavalin A coupled to Sepharose but not to other lectins or glycoproteins.
