A marine analgesic peptide, Contulakin-G, and neurotensin are distinct agonists for neurotensin receptors: uncovering structural determinants of desensitization properties [PDF]
, 2015 Neurotensin receptors have been studied as molecular targets for the treatment of pain, schizophrenia, addiction, or cancer. Neurotensin (NT) and Contulakin-G, a glycopeptide isolated from a predatory cone snail Conus geographus, share a sequence ...

Three-Dimensional Structure of Conotoxin tx3a: A m-1 Branch Peptide of the M-Superfamily [PDF]
, 2008 The M-superfamily, one of eight major conotoxin superfamilies found in the venom of the cone snail, contains a Cys framework with disulfide-linked loops labeled 1, 2, and 3 (- CC1C2C3CC-). M-superfamily conotoxins can be divided into the m-1, -2, -3 and -

Exploring Use of a Protein Cage System for Producing Bioactive Peptides in Escherichia coli
Microbial Biotechnology, Volume 18, Issue 6, June 2025.Bioactive peptides can be difficult to manufacture biosynthetically. This study explored the use of bacteriophage P22 virus‐like particles to encapsulate recombinantly expressed bioactive peptides, enabling the production of therapeutically valuable linear and cyclic peptides in Escherichia coli.

FEBS Open Bio, Volume 15, Issue 3, Page 415-426, March 2025.Sea stars have remarkable regenerative capabilities. A peptide, KASH2, identified in the biofluid of the common sea star Asterias rubens appears to be involved with the wound‐healing response in the organism. Here, we show the 3D structure of KASH2 adopts a disulfide‐directed β‐hairpin fold, a fold only previously found in arachnids, and does not show ...
