- Dig2 is localized in the nucleus (judged by immunofluorescence). Tedford et al. 1997 PMID 9094309
- Dig2-GFP is localized in the nucleus. Localization is unchanged by pheromone exposure. van Drogen et al. 2001 PMID 11781566
- Dig2 interacts with Fus3, Kss1, and Ste12 as judged by yeast two-hybrid and co-immunoprecipitation. Tedford et al. 1997 PMID 9094309
- Dig1 and Dig2 are serve redundant functions for both invasive growth and mating response. Tedford et al. 1997 PMID 9094309
- Deletion of either of Dig1 or Dig2 by themselves has minimal effect on invasive growth (judged by morphology) and on mating response (judged by growth arrest (BAR1 strain), and Fus1 gene expression).
- Deletion of both Dig1 and Dig2 results in constitutive invasive growth.
- Deletion of both Dig1 and Dig2 results in constitutive expression of the Fus1 gene (50-fold above WT cells), although exposure to pheromone still results in a modest increase in Fus1 gene expression.
- Dig2 contains a putative MAPK docking site within residues 95-116, and Dig2(95-116) binds Fus3 and Kss1. Kusari et al. 2004 PMID 14734536
