A novel bioactive peptide named τ-AnmTx Ueq 12-1 (short name Ueq 12-1) was isolated and characterized from the sea anemone Urticina eques. Ueq 12-1 is unique among the variety of known sea anemone peptides in terms of its primary and spatial structure. It consists of 45 amino acids including 10 cysteine residues with an unusual distribution and represents a new group of sea anemone peptides. Th...

Hox and TALE proteins interact in a sea anemone, just as they do in flies and mice, indicating that the Hox-TALE system originated very early in animal evolution.

Feeney and Brooker introduce sea-anemone associated fish.

During the BIOACCESS Japanese cruises (1996 & 1998), active hydrothermalism and associated vent fauna were studied on the South-eastern Rift of Manus Basin (South-western Pacific). In the PACMANUS vent field, a conspicuous vent fauna was sampled, including an actinostolid sea anemone (Actiniaria) belonging to an undescribed genus and species. Pacmanactis hashimotoi gen. et spec. nov. is here de...

Associated bacteria from Stichodactyla haddoni are found maximum in tentacle tissues than the body tissue. There are eight associated bacterial species viz., Alcaligenes sp, Corynebacterium sp, Aeromonas sp, Sporosarcina sp, Renibacterium sp, Camobacterium sp1, Camobacterium sp2 and Salinococcus sp were recorded. The culture extracts from the associated bacterial species showed sensitivity agai...

The action of neurotoxins on tetrodotoxin-insensitive sodium channels in cultured rat muscle cells has been studied by ion flux methods. The alkaloid neurotoxins batrachotoxin, veratridine, and aconitine act at a common receptor site to cause persistent activation of sodium channels. Batrachotoxin is a full agonist, while veratridine and aconitine are partial agonists activating 8% and 1% of so...

Heart failure is one of the most prevalent causes of death in the western world. Sea anemone contains a myriad of short peptide neurotoxins affecting many pharmacological targets, several of which possess cardiotonic activity. In the present study we describe the isolation and characterization of AdE-1 (ion channel modifier), a novel cardiotonic peptide from the sea anemone Aiptasia diaphana, w...

The wild type red fluorescent protein eqFP578 (from sea anemone Entacmaea quadricolor, λ(ex) = 552 nm, λ(em) = 578 nm) and its bright far-red fluorescent variant Katushka (λ(ex) = 588 nm, λ(em) = 635 nm) are characterized by the pronounced pH dependence of their fluorescence. The crystal structures of eqFP578f (eqFP578 with two point mutations improving the protein folding) and Katushka have be...
