We have previously isolated several cDNA clones of mRNAs that have the unusual property of being localized to either the animal pole or the vegetal pole of frog eggs. To gain insight into the function of these maternal mRNAs we have determined their DNA sequence and deduced the sequence of the proteins they encode. Here we report that An2, an mRNA localized to the animal pole of Xenopus oocytes and eggs, codes for the alpha chain of mitochondrial ATPase. Furthermore, we compare the intracellular localization of the An2 mRNA and mitochondria in oocytes and eggs and find that they do not have the same degree of localization. In the light of these results we discuss possible reasons for the maternal localization of the An2 mRNA.
This research output has an Altmetric Attention Score of 6. 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 13 January 1998.
All research outputs
#7,633,119
of 34,518,147 outputs
Outputs from Proceedings of the National Academy of Sciences of the United States of America
#63,594
of 119,104 outputs
Outputs of similar age
#2,862
of 17,154 outputs
Outputs of similar age from Proceedings of the National Academy of Sciences of the United States of America
#90
of 317 outputs
Altmetric has tracked 34,518,147 research outputs across all sources so far. This one has received more attention than most of these and is in the 73rd percentile.
So far Altmetric has tracked 119,104 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 40.1. This one is in the 37th percentile – i.e., 37% of its peers scored the same or lower than it.
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 17,154 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 68% of its contemporaries.
We're also able to compare this research output to 317 others from the same source and published within six weeks on either side of this one. This one is in the 47th percentile – i.e., 47% of its contemporaries scored the same or lower than it.
