Special Issue Information
Dear Colleagues,
This is a continued issue of our successful Special Issue “G Protein-Coupled Receptors in Cell Signaling Transduction”.
G protein-coupled receptors (GPCRs) and their downstream signaling pathways are critical targets for current pharmacotherapy. More than one-third of the drugs in use today act on GPCRs either as agonists, inverse agonists, or antagonists; however, their therapeutic potential is not exhausted, especially since recent findings point to new pharmacotherapeutically relevant regulatory mechanisms. In particular, hitherto largely unknown non-classical or, as they are also termed, non-canonical regulatory mechanisms of GPCR signaling have been identified that can either modulate canonical signaling by G proteins or trigger unrelated signaling events. These pathways are governed by receptor classes other than GPCRs, and various non-receptor regulators, including activators of G protein signaling (AGS) proteins or phosphate transferring nucleoside diphosphate kinases (NDPKs). GPCR adapters, such as arrestins and regulators of G protein signaling (RGS), can exert additional functions distinct from the inactivation of G protein signaling. Original research articles, reviews, and communications on the (patho)physiological relevance of canonical as well as non-canonical GPCR signaling in biological processes, such as tumor progression, autophagy, and cell movement, which are crucial for major human diseases, including cancer, metabolic disorders, cardiovascular diseases, immune responses, and (neuro-)sensory defects, will be particularly appreciated.

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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
