Metric Options: CountsSelecting 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.

Book Chapter Description
Protein sumoylation is a reversible posttranslational modification that controls multiple processes during cell cycle progression. Frequently, SUMO synergistically targets various subunits in a protein complex to modulate its function, leading to what has been defined as protein group sumoylation. Different subunits in the RENT (regulator of nucleolar silencing and telophase) complex, including Net1, Sir2, and Cdc14, can be coupled to SUMO, making it difficult to ascertain the role of this modification. Here we describe a method to downregulate sumoylation in RENT, consisting in the fusion of a catalytic domain of the Ulp1 SUMO protease (Ulp Domain; UD) to the C-terminus of members in the complex using epitope tags as linkers. Targeting of the UD to specific loci can be simplified by transformation of PCR-amplified cassettes. The presence of the UD in the complex allows the concurrent downregulation of sumoylated species in the RENT complex, what can be easily monitored by pull-down of SUMO conjugates. This methodology can be applied to other protein complexes exhibiting group sumoylation.
