PERM-2 is a secreted protein that localizes to the surface of unfertilized oocytes and the embryonic eggshell; genetic and co-IP studies show that PERM-2 interacts with PERM-4 and CBD-1 to form a protein complex required for structural integrity of the vitelline layer of the eggshell.
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.
