During repair of a double-strand break (DSB) by gene conversion, one or both 3' ends of the DSB invade a homologous donor sequence and initiate new DNA synthesis. The use of the invading DNA strand as a primer for new DNA synthesis requires that any nonhomologous bases at the 3' end be removed. We have previously shown that removal of a 3' nonhomologous tail in Saccharomyces cerevisiae depends on the nucleotide excision repair endonuclease Rad1/Rad10, and also on the mismatch repair proteins Msh2 and Msh3. We now report that these four proteins are needed only when the nonhomologous ends of recombining DNA are 30 nucleotides (nt) long or longer. An additional protein, the helicase Srs2, is required for the RAD1-dependent removal of long 3' tails. We suggest that Srs2 acts to extend and stabilize the initial nascent joint between the invading single strand and its homolog. 3' tails shorter than 30 nt are removed by another mechanism that depends at least in part on the 3'-to-5' proofreading activity of DNA polymerase delta.
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 01 February 2022.
All research outputs
#5,140,275
of 34,357,314 outputs
Outputs from Molecular & Cellular Biology
#1,302
of 14,056 outputs
Outputs of similar age
#78,518
of 449,596 outputs
Outputs of similar age from Molecular & Cellular Biology
#1,005
of 10,454 outputs
Altmetric has tracked 34,357,314 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 14,056 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 79% 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 449,596 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 10,454 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 80% of its contemporaries.
