... bacterial secretion process–commonly known as the Sec system; work that will be published elsewhere. Below is a description of the alternative and contested models for protein translocation that we all have been contemplating for many years. This review will consider their pros and cons . 1 To whom...

...Vivek Malhotra; Patrik Erlmann; Cristina Nogueira Collagens are secreted into the extracellular space where they assemble into a large complex protein network to form basement membrane and extracellular matrix. Collagens are therefore essential for cell attachment, tissue organization...

... of the signals by the pollen tube. Several ovule-secreted peptides have been identified. Nevertheless, there are no exact findings on how these signals are perceived by the pollen tube. As a novel approach, we have improvised a modified SIV (semi- in vivo ) technique, SIV-PS (SIV pollen tube secretome...

... of the polarity pathways, analogies between fission yeast and other model systems can be useful to decipher how cells can actively define their shape by polarized growth.

... and the unconventional myosin motor proteins in classes 1c/1e, Va and VI are specifically involved in these final stages of secretion. In the present review, we examine the roles of these myosins in these stages of the secretory pathway and the implications of their roles for an enhanced understanding of secretion...

...I. Collinson Proteins destined for secretion, membrane insertion or organellar import contain signal sequences that direct them to the membrane. Once there, transport machines receive and translocate them appropriately across or into the membrane. The related SecY and Sec61 protein translocation...

... with nicotine 48 h after transduction, the fractional loss of fluorescent LDCVs was much greater than the fractional catecholamine secretion, implying selective release of newly assembled vesicles. This was confirmed using a fluorescent ‘timer’ construct that changes its fluorescence emission from green to red...

..., but not acute, stimulation of secretion by glucose. Thus, vesicles released during the first phase of insulin secretion exist largely within a translocation-independent pool. Kinesin-driven anterograde movement of vesicles is then necessary for the sustained (second phase) of insulin release. Kinesin may...
