Members of this family are involved in the negative regulation of gluconeogenesis. They are required for both proteosome-dependent and vacuolar catabolite degradation of fructose-1,6-bisphosphatase (FBPase), where they probably regulate FBPase targeting from the FBPase-containing vesicles to the vacuole [1][2].

1: Catabolite degradation of fructose-1,6-bisphosphatase in the yeast Saccharomyces cerevisiae: a genome-wide screen identifies eight novel GID genes and indicates the existence of two degradation pathways.

2: Vid24p, a novel protein localized to the fructose-1, 6-bisphosphatase-containing vesicles, regulates targeting of fructose-1,6-bisphosphatase from the vesicles to the vacuole for degradation. Chiang MC, Chiang HL; J Cell Biol. 1998;140:1347-1356. PMID:9508768
