The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.6 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.2 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00058 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.345 SNIP: 0.46 CiteScore™:: 2.5 H-Index: 67

摘要

Nuclear architecture is remodeled during interphase in response to changes in gene activity as well as to changing structural and functional requirements during cell division. Using the monoclonal antibody mAb2A, we have identified two proteins that appear to play important roles in these processes: JIL-1 is a tandem serine-threonine kinase implicated in the regulation of chromatin structure, whereas Skeletor is a novel protein participating in structural nuclear remodeling during the cell cycle. Antibody staining and live imaging of JIL-1 -GFP transgenic flies show that JIL-1 localizes to the gene-rich interband regions of larval polytene chromosomes and is upregulated almost twofold on the hypertranscribed male X chromosome compared with autosomes. We propose that JIL-1 may play a role in transcriptional control potentially by regulating chromatin structure. The other mAb2A antigen, Skeletor, is distributed in a nuclear meshwork pattern that can be observed in stereo pair images to reorganize during the cell cycle to form a spindle-like structure at prometaphase that is distinct from the microtubule spindle apparatus. Taking advantage of the powerful molecular and genetic approaches offered in Drosophila, the study of these two proteins promises to yield new insight into what defines nuclear architecture at the molecular level and how its remodeling is regulated.
