The LC1 N-terminus is important for motility. (a) Drawing depicts the flagellar axoneme of T. brucei and model for LC1 function with C-terminus (C) and N-terminus (N) contributing to interaction with the outer dynein gamma heavy chain (γ-HC) and microtubule doublet, respectively. Based on19,20. (b) Mean squared displacement (MSD) was determined for the indicated cell lines as described in Methods. Bold lines represent the average MSD across seven biological replicates from three independent experiments (>400 cells tracked per cell line per replicate for a total of >4200 cells tracked per cell line). Dashed lines represent the standard error of the mean between seven replicates. Inset shows the HA-tag and point mutant status of LC1 in each cell line. Asterisks represent K203A and R210A substitutions in LC1. (c) Survival curves for mice infected with the indicated cell lines. The HA-tag and point mutant status are as indicated in the panel b inset.
