- plk-2 : sun-1
"PLK-2 is required for SUN-1/ZYG-12 patch formation and coimmunoprecipitates with SUN-1."
- ced-4 : sun-1
"matefin/SUN-1 binds CED-4 and is specifically required for CED-4 translocation and maintenance at the NE."
- Interaction involving sun-1
"The amino-terminal region of SUN-1 can interact with itself, but not with HIM-8 or ZIM-3, in a Y2H assay."
- kdp-1 : sun-1
KDP-1 is a nuclear envelope KASH protein that interacts with SUN-1 and UNC-84, and it is required for cell cycle progression.
