Plasma membrane H+‐ATPase pumps build up the electrochemical H+ gradients that energize most other transport processes into and out of plant cells through channel proteins and secondary active carriers. In Arabidopsis thaliana , the AUTOINHIBITED PLASMA MEMBRANE H+‐ATPases AHA1, AHA2 and AHA7 ...
but also the cell wall lacked the ability to serve as a barrier against the propagation of extracellular ice, whereas in the chilling-resistant plant cells that we examined, not only the plasma membrane but also the cell wall acted as a barrier against the propagation of extra-cellular ice. ...
138 interacts with HDAC6 and Arl13b. The outer and inner leaflets of the plasma membrane are shown with membrane cholesterol (red), highlighting the association of CD133 with cholesterol-dependent membrane microdomains. Amino acid numbering is based on the human splice variant CD133.s2; the appro...
Due to the saturated acyl chains of its core lipids, GPIs preferentially insert in sphingolipid-rich domains of the plasma membrane outer leaflet, and the capacity of GPIanchored proteins to participate in transmembrane signalling depends on this property. GPI-anchored proteins can be made to ...
ARF6 localizes to the plasma membrane and endosomal compartments, in which it regulates clathrin-dependent endocytic membrane trafficking, as well as the trafficking and sorting of molecules that lack cytoplasmic AP-2 and clathrin sorting sequences, through a unique endocytic route. ARF6 has also ...
These are small solid structures located at different points along the lymphatic system. Their function is to trap the microorganisms or other antigens, that enter the lymph and tissue fluid. Therefore, the antigens trapped in the lymph nodes are responsible for the activation of lymphocytes presen...
Alterations in calcium signaling and/or the expression of calcium pumps and channels are an increasingly recognized property of some cancer cells.Alterations in the expression of plasma membrane calcium ATPase(PMCA) isoforms have been reported in a variety of cancer types,including those of breast and...
Keratinocytes cultured in high calcium produce much more intense immunofluorescence of intercellular E- and P-cadherin than those cells grown in low calcium. E-cadherins on the plasma membrane of the keratinocytes are shifted to desmosomes under physiological conditions, and therein may express an ...
Membrane rafts potentially have crucial physiological roles across cell types that range from immune cells to cancer cells. Membrane domains are conserved throughout the domains of life, which supports their functional importance in biological systems. Abstract Cellular plasma membranes are laterally heterog...
CD147 is a widely expressed integral plasma membrane glycoprotein and has been involved in a variety of physiological and pathological activities in combination with different partners, including cyclophilins, caveolin-1, monocarboxylate transporters, and integrins. Recent data demonstrate that both CyPA an...
