In BHK-21 cells, overexpression of the wild-type Rab22a caused formation of abnormally large vacuole-like structures containing the early-endosomal antigen EEA1 but not Rab11, a marker of recycling endosomes or the late-endosomal/lysosomal markers LAMP-1 and lyso-bis-phosphatidic acid. In HeLa cells, overexpressed Rab22a was found on smaller EEA1-positive endosomes, but a portion of the protein was also found in the Golgi complex. Using the yeast two-hybrid system and a biochemical pull-down assay, the GTP-bound form of Rab22a was found to interact with the N-terminus of EEA1. In HeLa cells overexpressing Rab22a or its mutants affected in the GTPase cycle, no significant changes were observed in the uptake of Alexa-transferrin. However, the GTPase-deficient Rab22a Q64L mutant caused a redistribution of transferrin-positive endosomes to the leading edges of cells and a fragmentation of the Golgi complex. In BHK cells, the Q64L mutant caused the accumulation of a fluid phase marker, TRITC-dextran, and a lysosomal hydrolase, aspartylglucosaminidase, in abnormal vacuole-like structures that contained both early and late endosome markers. Both the wild-type Rab22a and the Q64L mutant were found to interfere with the degradation of EGF. These results suggest that Rab22a may regulate the dynamic interactions of endosomal compartments and it may be involved in the communication between the biosynthetic and early endocytic pathways."xsd:string |
