Predicted to enable small GTPase binding activity and zinc ion binding activity. Predicted to contribute to Rab geranylgeranyltransferase activity. Involved in PERK-mediated unfolded protein response. Predicted to be part of Rab-protein geranylgeranyltransferase complex. Expressed in head; intestine; and tail. Is an ortholog of human RABGGTB (Rab geranylgeranyltransferase subunit beta).
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.
