==Enigma family: PDZ/LIM-domain proteins of the cytoskeleton==


Three member proteins have extensively been described and characterized within this subfamily: '''Enigma''' protein, '''Enigma Homologue''' (ENH) protein and '''ZASP/Cypher/Oracle''' ('ZASP'<ref>PMID:10427098</ref> being the human orthologue of 'Cypher'<ref>PMID:10391924</ref> which is found in mouse and also identified by independent researchers who named it 'Oracle'<ref>PMID:10727866</ref>). Didactically, protein members of the enigma subfamily typically possess within their structure: '''(1)''' an N-terminal PDZ domain (a domain which is named after the first three proteins where it was initially characterized i.e. '''P'''SD 95, '''D'''isc large protein and '''Z'''onula Occludens 1), and '''(2)''' three C-terminal LIM domain (a domain which is named after the first three proteins where it was characterized i.e. '''L'''in-11, '''I'''sl1 and '''M'''ec-3)<ref>PMID:20042479</ref>. The member proteins have all been located to the mammalian muscle cells, some specific to the heart and skeletal muscle Z-disk. They interact via their PDZ domains with motor protein components of the Z-disk and also recruit signalling molecules via their LIM domains or internal motifs, for example ''ZM motif'' (ZASP-like motif which is sandwiched between the PDZ- and LIM-domains in ZASP)<ref>doi:10.1161/CIRCRESAHA.110.225615</ref>. These interactions via their PDZ- and LIM-domains have been suggested to be important for targeting/sustaining interacting protein complexes within the sarcomere for a physiologically functional muscle.

These interactions via their PDZ- and LIM-domains suggest roles important for targeting/sustaining interacting protein complexes within the myofibrillar sarcomere for a physiologically functional muscle.
