Special Issue Information
Dear Colleagues,
Ubiquitination is a pivotal regulatory mechanism for nearly all major cellular processes. For all eukaryotic organisms, it is essential for the growth and development of and the response to biotic and abiotic stresses. When catalyzing using many conjugation and deconjugation enzymes, the small and evolutionary conserved ubiquitin could be assembled and dynamically modulated on various protein substrates into highly diverged ubiquitin signals: ubiquitin monomer and ubiquitin chains with homogeneous, mixed, or branched linkages of various lengths. Depending on the different ubiquitin signals assembled, the outcomes of modified substrates could be rather distinct such as degradation by 26S proteasome, endocytosis, or the autophagy pathway. Various ubiquitin signals could also provide interfaces for relaying signal transduction pathways or for recruiting epigenetic regulatory and DNA repairing machineries. While the majority of ubiquitination studies focus on conjugation and deconjugation enzyme components and their corresponding physiological functions, little information is available for specific ubiquitin signals assembled on particular substrates in vivo or on corresponding ubiquitin binding factors for deciphering various ubiquitin signals and associated mechanisms en route to various cellular processes. This Special Issue will be focused on ubiquitin signal assembles on specific substrates and ubiquitin binding proteins involved in deciphering various ubiquitin signals for various cellular processes, such as various degradation pathways, signal transduction, epigenetic regulation, and DNA repairing. All related original articles, up-to-date reviews, and methodology papers will all be considered.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
