To map the binding sites involved in channel formation, synthetic peptides representing sequences of connexin 32 were tested for their ability to inhibit cell-cell channel formation. Both large peptides representing most of the two presumed extracellular loops of connexin32 and shorter peptides representing subsets of these larger peptides were found to inhibit cell-cell channel formation. The properties of the peptide inhibition suggested that the binding site is complex, involving several segments of both extracellular loops. One of the peptides (a 12-mer) did not inhibit but instead was found to form channels in membranes. Both in oocyte membranes and in bilayers, the channels formed by the peptide were asymmetrically voltage dependent. Their unit conductances ranged from 20 to 160 pS. These data are discussed in the form of a model in which the connexin sequence represented by the peptide is part of a beta structure providing the lining of the channel pore.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 9. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 30 June 2026.
All research outputs
#5,056,682
of 34,054,827 outputs
Outputs from Biophysical Journal
#1,205
of 12,233 outputs
Outputs of similar age
#3,046
of 31,485 outputs
Outputs of similar age from Biophysical Journal
#2
of 33 outputs
Altmetric has tracked 34,054,827 research outputs across all sources so far. Compared to these this one has done well and is in the 83rd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 12,233 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.4. This one has done well, scoring higher than 87% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 31,485 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 82% of its contemporaries.
We're also able to compare this research output to 33 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 90% of its contemporaries.
