Special Issue Information

Dear Colleagues,

Tumor Necrosis Factor Receptor-Associated Factor 1 (TRAF1) is a pivotal molecule in many immune and non-immune cellular processes. Acting as an essential adapter protein, TRAF1 plays a central role in recruiting key components of inflammatory signalling pathways (e.g., Toll-like receptors, Nod-like receptors, and RIG-I-like receptors), TNFRs responsible for signalling survival (e.g., CD40 and 4-1BB), inflammasomes, and apoptosis signal-regulating kinase 1 (ASK1), a mitogen-activated protein kinase involved in stress response, apoptosis, inflammation, and cell differentiation. The multi-faceted role of TRAF1 in controlling inflammation and cell survival stems from its ability to activate or inhibit these signalling pathways and downstream transcription factors. Importantly, TRAF1 has been associated with several human diseases, including inflammation-driven diseases (e.g., rheumatoid arthritis, gout, and sepsis), ischemia of the heart and brain, and liver fibrosis. TRAF1 is also linked to blood cancers, including chronic lymphocytic leukemia (CLL), lymphomas, and multiple myeloma. Consequently, further research is required to explore the potential for targeting TRAF1 in complex inflammatory diseases and cancers involving multiple signalling pathways.

This Special Issue compiles the latest research findings on TRAF1's role in regulating inflammatory responses and cellular survival.

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. Biomolecules is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). 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.

Tumor necrosis factor receptor-associated factor (TRAF) proteins play pivotal roles in a multitude of cellular signaling pathways, encompassing immune response, cell fate determination, development, and thrombosis. Their involvement in these processes hinges largely on their ability to interact directly with diverse receptors via the TRAF domain. Given the limited binding interface, understanding how specific TRAF domains engage with various receptors and how structurally similar binding interfaces of TRAF family members adapt their distinct binding partners has been the subject of extensive structural investigations over several decades. This review presents an in-depth exploration of the current insights into the structural and molecular diversity exhibited by the TRAF domain and TRAF-binding motifs across a range of receptors, with a specific focus on TRAF1.
