Enigma family: PDZ- and LIM-domain protein of the cytoskeleton
Three proteins have extensively been described and characterized within this subfamily: Enigma, Enigma Homologue (ENH) protein and ZASP/Cypher ('ZASP' being the human orthologue of 'Cypher' which is found in mouse and also identified by independent researchers who named it 'Oracle').
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. PSD 95, Disc large protein and Zonula 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. Lin-11, Isl1 and Mec-3).
The member proteins have all been located to the mammalian striated muscle, specifically in 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 thier LIM domain or internal motifs, for example ZM motif (ZASP-like motif which is sandwiched between the PDZ- and LIM-domains in ZASP).
These interactions via their PDZ- and LIM-domains have been suggested to be important for scaffolding interacting proteins in the sarcomere in order to maintain a proper architecture and physiologically functional muscle.
