Article Title: Multiple ciliary localization signals control INPP5E ciliary targeting

doi: 10.7554/elife.78383

Figure Lengend Snippet: Figure 1. INPP5E catalytic domain encompasses FDRxLYL motif and is required for ciliary targeting. (a) Top diagram represents full length human INPP5E protein sequence (aa 1–644). Depicted are the proline-rich region (aa 10–242, Uniprot), the previously reported ciliary localization signal (FDRxLYL, aa 609–615 Humbert et al., 2012), and the CaaX box driving farnesylation (aa 641–644). Also shown is the inositol polyphosphate 5-phosphatase catalytic domain, whose most conserved core corresponds to InterPro domain IPR000300 (aa 297–599), but which actually spans aa
