Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A connexin construct consisting of bacterial β-galactosidase fused to the C-terminus of connexin43 (Cx43/β-gal) was used to examine Cx43 assembly in NIH 3T3 cells. Cx43/β-gal is retained in a perinuclear compartment and inhibits Cx43 transport to the cell surface. The intracellular connexin pool trapped by Cx43/β-gal was retained in a compartment that co-localized with a medial Golgi apparatus marker by immunofluorescence microscopy and that was readily disassembled by treatment with brefeldin A. Further analysis by sucrose gradient fractionation showed that Cx43 and Cx43/β-gal were assembled into a sub-hexameric complex, and that Cx43/β-gal expression also inhibited Cx43 assembly into hemichannels. While this is consistent with Cx43 hemichannel assembly in the trans Golgi network (TGN), these data also suggest that the dominant negative effect of Cx43/β-gal on Cx43 trafficking may reflect a putative sub-hexameric assembly intermediate formed in the Golgi apparatus. © 2001, Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
