Conkazal‐M1 from the MKAVA family of conotoxins: A dual‐function protease inhibitor and neuroactive peptide

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Marine cone snails produce a diverse array of bioactive peptides, known as conotoxins, in their venom. Given their high target potency and specificity, conotoxins are attractive compounds for the development of precision research tools and pharmacological agents.

Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...
