| description | The tripartite DENN (after differentially expressed in neoplastic versusnormal cells) domain is found in several proteins involved in Rab-mediatedprocesses or regulation of MAPKs (Mitogen-activated preotein kinases)signaling pathways. It actually consists of three parts as the original DENNdomain is always encircled on both sides by more divergent domains, calleduDENN (after upstream DENN) and dDENN (for downstream DENN). The tripartiteDENN domain is found associated with other domains, such as RUN, PLAT, PH, PPR, WD-40, GRAM or C1. The function of DENN domain remains to date unclear, although it appears to represent a good candidate for a GTP/GDP exchange activity [, ].The general characteristics of DENN domains - three regions dDENN, DENNitself, and uDENN having different patterns of sequence conservation andseparated by sequences of variable length - suggest that they are composed ofat least three sub-domains which may feature distinct folds but which arealways associated due to functional and/or structural constraints [].Some proteins known to contain a tripartite DENN domain are listed below:Rat Rab3 GDP/GTP exchange protein (Rab3GEP) Human mitogen-activated protein kinase activating protein containing deathdomain (MADD). It is orthologous to Rab3GEP Caenorhabditis elegans regulator of presynaptic activity aex-3, theortholog of Rab3GEP Mouse Rab6 interacting protein 1 (Rab6IP1) Human SET domain-binding factor 1(SBF1) Human suppressor of tumoreginicity 5 (ST5) Human C-MYC promoter-binding protein IRLB This entry represents the core or cDENN domain. |
