Special Issue Information

Dear Colleagues,

Leucine Rich Repeats (LRRs) consisting of 20–30 amino acids in length repeat 2–100 times in tandem. Individual LRRs are generally separated into a hallmark motif, a highly conserved segment (HCS) with the consensus of LxxLxLxxNxL or LxxLxLxxCxxL, and a variable segment (VS), in which “L” is Leu, Val, or Ile, “N” is Asn, “C” is Cys, and “x” is any amino acid. A variety of LRR classes or types have been recognized. Short β-strands in the repeating units stack in parallell and form a super helix arrangement (called a solenoid structure). LRRs are present in over 900,000 proteins ranging from viruses to eukaryotes. LRR proteins are involved in a variety of biological processes, including the immune response, signal transduction, cell adhesion, disease resistance, apoptosis, ubiquitin-related processes, DNA repair, recombination, transcription, RNA processing, nuclear mRNA transport, neuronal development, and collagen fibrillogenesis. Their functions are mostly expressed through protein or ligand interactions. Mutations of LRR protein genes are associated with various human diseases. 

The goal of this Special Issue is to get a deep understanding of the correlations between sequence, structure, ligand interactions, and functions. We welcome all research related to the structures of LRR proteins by experimental and bioinformatics approaches. Additionally, sequence analyses and evolutionary research will be welcome. Original scientific reports, review articles, commentary, and perspective papers are accepted.

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 250 words) can be sent to the Editorial Office for assessment.

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. Biology is an international peer-reviewed open access semimonthly 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.

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.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.
