The secretion of biologically active peptides and hormones by CE cells may follow unidirectional secretion from NPE cells into the AqH side. However, given the atypical cell polarity of the NPE and PE cell layers in vivo, the trafficking of proteins and peptides could also occur from the PE ...
Active transport is the same as passive transport only without the use of a transport protein. Transport Proteins: Substances are moved into or out of a cell through a variety of different mechanisms. Some substances pass directly through the cell membrane, wher...
It is estimated that two-thirds of all proteins in higher organisms are composed of multiple domains, many of them containing discontinuous folds. However, to date, most in vitro protein folding studies have focused on small, single-domain proteins. As a
The observations strongly suggest that the selective transport of the coelomic fluid proteins into the oocytes of specific stages is mediated by the membrane proteins, which appear to be receptors. 展开 关键词: Oogenesis polychaete coelomic fluid proteins membrane proteins transport ...
The purified, transportactive MRP2 may serve to identify additional interacting proteins in the apical membrane of polarized cells. 展开 关键词: ABC transporter calnexin LTC4 transport multidrug resistance protein 2 reconstitution (of transport activity ...
Protein expressionrepresents the accumulation or end product ofgeneticinformation. DNA is transcribed intoRNA, which is then translated into proteins. Therefore the detection of proteins and their active forms (most often phosphorylated) represents an important step in the global understanding ofcancer bio...
Milk proteins and milk protein-derived peptides have been widely studied for their health enhancing properties. This chapter presents the updated scientific knowledge on the bioactive properties of milk protein-derived peptides. The different bioactive p
It may, however, model cognitive aspects of schizophrenia. Dysbindin-1 may have diverse functions. Among these are the promotion of cell growth and proliferation, protection against neuronal apoptosis, facilitation of axon, dendrite, and dendritic spine growth, regulation of AP-3 cargo transport to...
Multiple molecular mechanisms involved in the secretion, uptake and transport of pathological seeds have been identified. Neurodegenerative disease-related pathological proteins are conformationally diverse. Various factors can modulate the transmission process, including neuronal activity, glial cells, genetic ri...
