Attractin (IPR012529)

Short name: Attractin

Overlapping homologous superfamilies

Family relationships



This family consists of the attractin family of water-borne pheromone. 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].
