Predicted to enable guanyl-nucleotide exchange factor activity. Involved in endosomal transport; organelle organization; and secretion. Located in Golgi cis cisterna and endoplasmic reticulum exit site. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease dominant intermediate A. Is an ortholog of human GBF1 (golgi brefeldin A resistant guanine nucleotide exchange factor 1).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
