The Golgi-associated protein golgin A1 (GOLGA1, golgin-97) was first isolated as a Golgi complex autoantigen associated with the autoimmune disorder Sjogren's syndrome (1). The golgin-97 protein contains a carboxy-terminal GRIP domain and is a commonly used trans-Golgi network (TGN) marker. All four known mammalian GRIP domain-containing proteins (golgin-97, golgin-245, GCC88 and GCC185) are found in the TGN, share extensive alpha-helical structure, and form homodimers (2). While all four golgin proteins localize to the TGN, they exhibit different membrane-binding abilities and are found in distinct TGN regions (3). Golgin-97 and golgin-245 are targeted to the trans-Golgi network through an interaction between their GRIP domains and the Arl1 protein switch II region (4). Overexpression studies and siRNA assays with GRIP domain-containing proteins suggest that these proteins help to maintain trans-Golgi network integrity and function by controlling localization of TGN resident proteins (5). By using a Shiga toxin B fragment (STxB)-based in vitro transport assay and an E-cadherin transport model system, golgin-97 and its effector Arl1-GTP were shown to play a role in trans-Golgi endosomal trafficking (6,7). Research studies also suggest that golgin-97 may play a role in poxvirus morphogenesis and maturation (8,9).
