SMART accession number:SM01227
Description: This domain is found in proteins carrying other domains known to be involved in intracellular signalling pathways indicating that it might also be involved in these pathways. It has 4 highly conserved cysteine residues, suggesting that it can bind zinc ions. Moreover, it is found repeated in some members of this family. This may indicate that these domains are able to interact with one another, raising the possibility that this domain mediates heterodimerisation.
