Homologous Superfamily

Attractin superfamily (IPR036585)

Short name: Attractin_sf

Overlapping entries


This superfamily consists of attractin water-borne pheromones. Mate attraction in Aplysia involves a long-distance water-borne signal in the form of the attractin peptide that is released during egg laying. These peptides contain 6 conserved cysteines and are folded into 2 antiparallel helices. The second helix contains the IEECKTS sequence conserved in Aplysia attractins [PMID: 15118100].
