Piezo Proteins: Regulators of Mechanosensation and Other Cellular Processes

Piezo proteins: regulators of mechanosensation and other cellular processes.

Piezo proteins have recently been identified as ion channels mediating mechanosensory transduction in mammalian cells. Characterization of these channels has yielded important insights into mechanisms of somatosensation, as well as other mechano-associated biologic processes such as sensing of shear stress, particularly in the vasculature, and regulation of urine flow and bladder distention.

functional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner

نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...

Heat shock proteins in thermotolerance and other cellular processes.

Heat shock proteins appear to be causatively involved in the acquisition of thermotolerance in prokaryotes but not in eukaryotes. Further, the enhanced synthesis of hsps may be necessary for some cellular responses to stress but not others. In prokaryotic cells the development of thermotolerance, as measured by cell survival, is dependent upon protein synthesis. However, in eukaryotes, enhanced...

Extracellular Proteins Needed for C. elegans Mechanosensation

The mec-5 and mec-9 genes encode putative extracellular proteins that allow a set of six touch receptor neurons in C. elegans to respond to gentle touch. MEC-5 is a collagen made by the epidermal cells that surround the touch cells. Mutations causing touch insensitivity affect the Gly-X-Y repeats of this collagen. mec-9 produces two transcripts, the larger of which is expressed in the touch cel...
