Epidermal scale growth, allometry and function in non‐avian dinosaurs and extant reptiles

open access: yesJournal of Anatomy, Volume 247, Issue 2, Page 250-283, August 2025.
Scale shapes in non‐avian dinosaurs and extant reptiles are mostly retained through growth. However, positive scale allometry and proportional differences in scale breadth are also detected, which are likely associated with changing body proportions. Based on their generally conserved morphology and impracticality for visual display, the enlarged size ...

An N‐Terminally Elongated Peptide From Conus rolani Defines a New Class of Ribbon α‐Conotoxins Targeting Muscle nAChRs

open access: yesThe FASEB Journal, Volume 39, Issue 12, 30 June 2025.
α‐RoIA is an atypical N‐terminally elongated conotoxin discovered in Conus rolani. N‐terminal elongation delays activity in vivo; however, this elongation must be removed to block muscle nicotinic acetylcholine receptors (nAChRs). Only the truncated ribbon isoform of RoIA blocks muscle nAChRs.
