SGLT3 is not a transporter but instead acts as a glucosensor generating an inwardly directed flux of Na+ that causes membrane depolarization 117.
In 1999, in an article commemorating the Walkman's twentieth anniversary, the reporter Phil Patton wrote, "The Walkman and its rivals quickly became a landmark in the history of media and a symbol of an inwardly focused era".
In HEK293 cells, PCFT transport was insensitive to membrane potential, suggesting potential-independent, non-electrogenic transport in this model, although there was still a requirement for an inwardly directed proton gradient.
"Dying City," staged at Lincoln Center (and previously at the Royal Court in London), was an inwardly burrowing psychological drama, a portrait of a young war widow in New York and the men who have warped her life.
The other form, though still an inwardly directed emotion, is a sense of satisfaction and contentment in who you are as a person and even as a culture.
The specificity of this interaction was demonstrated using anti-Kir2.1 antibody as a negative control; Kir2.1 is an inwardly rectifying potassium channel that is highly expressed in the brain [33], and does not interact with KCNE1 [34].
Mammalian PSD-95 is a MAGUK which binds Kir4.1, an inwardly rectifying K+ channel expressed in glial cells and also clusters it to cell membranes in vitro [ 21].
The MacCannell et al. model includes four membrane currents: an inwardly rectifying K+ current, a time- and voltage-dependent delayed-rectifier K+ current, an electrogenic Na+/K+-ATPase, and a time-independent background Na+ conductance.
The reconstructions show that there exist several distinct functional groups of ommatidia in the visual surface (Fig. 1B3), orientated downwards and backward, laterally, and to the front, but the most conspicious is an inwardly orientated one with a high acuity.
The membrane voltage was clamped to −60 mV and 3 μM 5-HT was applied to the cell; 5-HT provoked an inwardly directed current that reached a steady amplitude during the exposure time (10 s).
