Model of the LC1 localization within the γ head domain and the axoneme. (A) Previous model of LC1 localization. Two copies of LC1 were assumed to bind to the AAA+ ring of the γ head domain. Inside the axoneme, LC1 was presumed to tether the AAA+ ring to the A-tubule of DMT. The model was adopted from Patel-King and King (2009). (B) A new model of LC1 localization. One copy of LC1 is believed to locate on the γ MTBD region with its N-terminus oriented toward the tip and C-terminus toward the base. In this model, LC1 interacts with the B-tubule of the DMT together with the γ MTBD inside the axoneme. LC1 is likely to regulate OAD activity by modulating the affinity of the γ MTBD for the B-tubule. Note that the LC1-binding site within the MTBD region was not determined in this study.
