Is member of a fraction that shows antiangiogenic activity, since it inhibits human microvascular endothelial cells (HMEC) tubulogenesis (PubMed:29671760). This protein could be a kunitz-type inhibitor with a RGD motif that could block angiogenesis in binding on integrins (Probable). Blocks Kv3 voltage-gated potassium channels (By similarity). Reduces blood pressure (By similarity). Moderately expressed in the ectodermal tissue from the distal and proximal tentacles, body wall, and oral disk. In contrast to BDS-1, may have an alpha-helix which could be located at the C-terminal domain. Belongs to the sea anemone type 3 (BDS) potassium channel toxin family. Opinions are divided on whether Anemonia viridis (Forsskal, 1775) and Anemonia sulcata (Pennant, 1777) are separate species.
