function:Rab9 effector required for endosome to trans-Golgi network (TGN) transport.,PTM:Phosphorylated on Ser residues most probably by PIP5K3.,similarity:Contains 5 Kelch repeats.,subcellular location:Interaction with PIP5K3 and subsequent phosphorylation recruits it to the endosomal membrane.,subunit:Interacts with PIP5K3. Interacts with RAB9 in its GTP-bound conformation.,
Cytoplasm. Endosome membrane . Interaction with PIKFYVE and subsequent phosphorylation recruits it to the endosomal membrane. .
