Nerve net Nerve net A nerve net consists of interconnected neurons lacking a brain or any form of cephalization. While organisms with bilateral body symmetry are normally associated with a central nervous system, organisms with radial symmetry are associated with nerve nets. Nerve nets can be found in members of the Cnidaria, Ctenophora, and Echinodermata phyla, all of which are found in marine environments. Nerve nets can provide animals with the ability to sense objects through the use of the sensory neurons within the nerve net. The nerve net is the simplest form of a nervous system found in multicellular organisms. Unlike
Death Domain database For example, DED will only bind with DED, CARD-CARD, PYD-PYD and DD-DD. These homotypic interactions are with only two members of the same domain (or on rare occasions with more) and there has been no evidence to suggest that these domains have heterotypic interactions with one another. DED domains are highly conserved in the Chordata phylum and can also be found in smaller percentages in the Echinodermata phylum and viruses. DED-containing proteins are associated with apoptosis regulation with caspase protein interaction and have been notably documented in mammals. DED domains have been known to interact with other domains and include:
