STRIPAK associates with Rabex5-Rabaptin5 to promote Rab5-dependent early endosome formation and EGFR transport
His Domain Protein Tyrosine Phosphatase (HD-PTP) is required for multivesicular body (MVB) formation and endosome maturation, with Rab5-GTP levels raised upon HD-PTP depletion (Parkinson et al., 2021. doi: 10/1242/jcs.259192). Mass Spectrometry-based interactomics revealed that HD-PTP depletion increased association of Rabaptin5, a component of the early endosome Rabex5-Rabaptin5 Rab5-GEF, with…
