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
Objective: Around one-fourth of the Komagataella phaffii genes encode hypothetical proteins with unknown functions. However, lack of powerful tools for genetic screening in K. phaffii significantly limits the functional analysis of these unknown genes. Transposon mutagenesis has been utilized as an insertional mutagenesis tool in many other organisms and would be extremely valuable if it could be applied in K. phaffii. Results: In this study, we investigated in K. phaffii the transposition activity and efficiency of piggyBac (PB) transposon, a DNA transposon from the cabbage looper moth Trichoplusia ni through the integrated-plasmid system. We also designed a binary-plasmid system which could generate stable mutants. Finally we evaluated the quality of this mutagenesis system by a simple screening for functional genes involved in K. phaffii carbon catabolite repression. Conclusions: Our results demonstrate that PB-mediated mutagenesis could be a feasible and useful tool for functional gene screening in K. phaffii.
