Variants of the human RAD52 gene confer defects in ionizing radiation resistance and homologous recombination repair in budding yeast
Alissa D. Clear1,2,3, Glenn M. Manthey1,2, Olivia Lewis4,5, Isabelle Y. Lopez4,6, Rossana Rico4,7, Shannon Owens8,9, M. Cristina Negritto10, Elise W. Wolf10,11, Jason Xu10,12, Nikola Kenjić13, J. Jefferson P. Perry13, Aaron W. Adamson14, Susan L. Neuhausen14, Adam M. Bailis1,2,15
RAD52 is a key protein in DNA repair and suppresses DNA damage in yeast; however, certain variants affecting BRCA2 mutations fail to correct HRR defects. This suggests that HsRAD52 aids multiple DNA repair mechanisms and could be targeted for use in treating BRCA2-deficient cancers.

Peer-reviewed, open-access research using unicellular organisms (and multicellular microorganisms) to understand cellular responses and human disease.
The journal (founded in 2014) is led by its Editors-in-Chief Frank Madeo, Didac Carmona-Gutierrez, and Guido Kroemer
Microbial Cell has been publishing original scientific literature since 2014, and from the very beginning has been managed by active scientists through an independent Publishing House (Shared science Publishers). The journal was conceived as a platform to acknowledge the importance of unicellular organisms, both as model systems as well as in the biological context of human health and disease.
Ever since, Microbial Cell has very positively developed and strongly grown into a respected journal in the unicellular research community and even beyond. This scientific impact is reflected in the yearly number of citations obtained by articles published in Microbial Cell, as recorded by the Web of Science (Clarivate, formerly Thomson/Reuters):
The scientific impact of Microbial Cell is also mirrored in a series of milestones:
2015: Microbial Cell is included in the Emerging Sources Citation Index (ESCI), a selection of developing journals drafted by Clarivate Analytics based on the candidate’s publishing standards, quality, editorial content, and citation data. Note: As an ESCI-selected journal, Microbial Cell is currently being evaluated in a rigorous and long process to determine an inclusion in the Science Citation Index Expanded (SCIE), which allows the official calculation of Clarivate Analytics’ impact factor.
2016: Microbial Cell is awarded the so-called DOAJ Seal by the selective Directory of Open Access Journals (DOAJ). The DOAJ Seal is an exclusive mark of certification for open access journals granted by DOAJ to journals that adhere to outstanding best practice and achieve an extra high and clear commitment to open access and high publishing standards.
2017: Microbial Cell is included in Pubmed Central (PMC), allowing the archiving of all the journal’s articles in PMC and PubMed.
