Golgin 97

CLONING

Griffith et al. (1997) used serum from a Sjogren syndrome (270150) patient with scleroderma to isolate a cDNA strand encoding a Golgi complex antigen from a HeLa cell cDNA library. The clone encoded a predicted 767-amino acid protein with a pI of 5.09, a granin motif (see 113705), and coiled-coil domains. On Western blots of HeLa cell extracts, the encoded protein migrated at 97 kD. Antibodies to the protein, which Griffith et al. (1997) named 'golgin-97,' stained the Golgi complex.

GENE FUNCTION

Wong and Munro (2014) selected 10 mammalian golgins that are conserved outside of vertebrates and found on different regions of the Golgi and ectopically expressed them at the mitochondria through attachment to a mitochondrial transmembrane domain in place of their C-terminal Golgi targeting domain. The authors then used the distribution of cargo-laden vesicles originating from different locations as a readout for the golgins' tethering activity. Wong and Munro (2014) found that golgin-97 (GOLGA1), golgin-245 (GOLGA4; 602509), and GCC88 (607418) were able to capture endosome-to-Golgi cargoes; GM130 (GOLGA2; 602580) and GMAP210 (TRIP11; 604505) were able to capture endoplasmic reticulum (ER)-to-Golgi cargoes; and golgin-84 (GOLGA5; 606918), TMF1 (601126), and GMAP210 were able to capture Golgi resident proteins. Furthermore, electron microscopy yielded ultrastructural evidence for the accumulation of vesicular membranes around mitochondria decorated with specific golgins. Wong and Munro (2014) concluded that these data suggested that not only do the golgins capture vesicles, they also exhibit specificity toward vesicles of different origins: from the endosomes, from the ER, or from within the Golgi itself. ...
