>cd04158 ARD1 ARD1 subfamily. ARD1 (ADP-ribosylation factor domain protein 1) is an unusual member of the Arf family. In addition to the C-terminal Arf domain, ARD1 has an additional 46-kDa N-terminal domain that contains a RING finger domain, two predicted B-Boxes, and a coiled-coil protein interaction motif. This domain belongs to the TRIM (tripartite motif) or RBCC (RING, B-Box, coiled-coil) family. Like most Arfs, the ARD1 Arf domain lacks detectable GTPase activity. However, unlike most Arfs, the full-length ARD1 protein has significant GTPase activity due to the GAP (GTPase-activating protein) activity exhibited by the 46-kDa N-terminal domain. The GAP domain of ARD1 is specific for its own Arf domain and does not bind other Arfs. The rate of GDP dissociation from the ARD1 Arf domain is slowed by the adjacent 15 amino acids, which act as a GDI (GDP-dissociation inhibitor) domain. ARD1 is ubiquitously expressed in cells and localizes to the Golgi and to the lysosomal membra
