| Summary |
Transcriptome analysis of specific mRNA interacting with KIF1C-GFP in HeLa Cells.
RNA localization and local translation are involved in a wide range of cellular functions. In mammals, a class of mRNAs localize to cytoplasmic protrusions in an APC dependent manner, with important roles during cell migration. Here, we investigated this localization mechanism. We found that the KIF1C motor interacts with many APC-dependent mRNAs and is required for their localization. Live cell imaging of localizing mRNAs further revealed rapid, active transport of single mRNAs over long distances, and showed that this requires both microtubules and KIF1C. Moreover, two color imaging directly revealed single mRNAs transported by single KIF1C motors, with the 3’UTR of localized mRNAs being sufficient to trigger KIF1C-dependent RNA transport and localization. These results reveal a general RNA transport pathway in mammalian cells, in which the KIF1C motor transports RNAs to cytoplasmic protrusions. Interestingly, KIF1C also transported its own mRNA suggesting a possible feedback loop acting at the level of mRNA transport.

| Overall design |
In total 4 samples; 2 control IP, 2 GFP-KIF1C IP. We performed RNA immunoprecipitation using the Affymetrix Human Transcriptome Array 2.0 chip on an Affymetrix platform (Thermo Fisher). Experiments were performed in duplicates, data were normalized and averaged,
