The small GTPase Rab5 promotes recruitment of the Ccz1-Mon1 guanosine exchange complex to endosomes to activate Rab7, which facilitates endosome fusion and maturation with lysosomes. 1D). In comparison, Rab7 mutants demonstrated a decreased amount of LTR-positive dots significantly, which could end up being rescued by showing YFP-Rab7 in the mutants (Amount 1, ECG). Because acidic… Continue reading The small GTPase Rab5 promotes recruitment of the Ccz1-Mon1 guanosine exchange
