.... The hepatopancreatic epithelium of the lobster Homarus americanus exhibits a Na + -dependent sugar transport system ( Ahearn et al., 1985 ) that resembles the familiar SGLT-1 transporter from vertebrates ( Wright et al., 1993 ) and a wide variety of Na + -dependent and Na + -independent amino acid transport...

All led to significant...

... of gill cells (rate of O 2 consumption, ATP content and amino acid transport). There was no indication of short-term volume regulation in the gill cells of mussels acclimated to salinity cycling. When exposed to cycling salinity, cell water space consistently increased to approximately 3 ml g −1 dry mass...

Using similar approaches, we are investigating the molecular characteristics of K + -coupled amino acid transporters in the larval lepidopteran insect...

... of Biologists Limited 1994 In summary, arginine is one of the three cationic amino acids transported by the functionally defined y + transport system (for a review, see White, 1985 ; Christensen, 1989 ). It now appears that the mCAT-1 and mCAT-2 gene products are likely to mediate y + -like transport...

...Manuel Palacín ABSTRACT The currently identified cDNA clones of mammalian amino acid transporters can be grouped into five different families. One family is composed of the proteins rBAT and the heavy chain (hc) of the cell surface antigen 4F2. RNAs encoding these two proteins induce a system b o...
