What is the function of this protein?
Guanine nucleotide exchange factor (GEF) which activates RAB21 and possibly RAB28 (By similarity).  Promotes the exchange of GDP to GTP, converting inactive GDP-bound Rab proteins into their active GTP-bound form (By similarity).  In response to starvation-induced autophagy, activates RAB21 which in turn binds to and regulates SNARE protein VAMP8 endolysosomal transport required for SNARE-mediated autophagosome-lysosome fusion (By similarity).  Acts as an adapter for the phosphatase MTMR2 (PubMed:16399794).  Increases MTMR2 catalytic activity towards phosphatidylinositol 3,5-bisphosphate and to a lesser extent towards phosphatidylinositol 3-phosphate (PubMed:16399794).
What are the official names of this protein?
Myotubularin-related protein 13, Inactive phosphatidylinositol 3-phosphatase 13, SET-binding factor 2.
What is the protein family that this protein belongs to?
Belongs to the protein-tyrosine phosphatase family. Non-receptor class myotubularin subfamily.
What are the subcellular locations of this protein?
Cytoplasm. Cytoplasm, perinuclear region. Membrane; Peripheral membrane protein. Endosome membrane; Peripheral membrane protein. Cell projection, axon. Note=Associated with membranes (By similarity). Localizes to vacuoles in hypo-osmotic conditions (PubMed:16399794). Membrane localization is likely to be mediated via its interaction with MTMR2 (PubMed:23297362).
