The following plasmids were used in this study: pMWH6C-µ2(160-435)50 (link), Myc-µ230 (link), Integrin α2-GFP29 (link), Integrin α4-GFP51 (link), integrin α5-GFP52 (link), dsRed-Rab753 (link), RFP-Rab553 (link), dsRed-Rab2129 (link), pPS-CFP2-αV-Integrin (Addgene, 57212), mCherry-Rab4a (Addgene, 55125), mCherry-Rab11 (Addgene, 55124) Point mutations were done by QuikChange II Mutagenesis kit (Agilent technologies) according to manufacturer’s instructions. All constructs were checked for integrity and correctness with sequencing.
