Regulatory Mechanism of Axonemal Dynein
Published in Keiko Hirose, Handbook of Dynein, 2019
The outer-arm dynein from sperm flagella contains several intermediate chains (Fig. 14.3). Two of them are WD-repeat intermediate chains with sequence similarities to Chlamydomonas IC78 and IC69 [110]. For example, sea urchin IC3 and IC2, Ciona IC1 and IC2, are orthologs of Chlamydomonas IC78 and IC69, respectively. Like those in Chlamydomonas flagella, WD-repeat ICs of outer-arm dynein from sperm flagella play a key role in assembly and binding of dynein on the A-tubule [41, 110]. Outer-arm dynein from sperm flagella also contains a unique intermediate chain with thioredoxin and nucleoside diphosphate kinase (TNDK) motifs [111, 114]. The molecular mass of this dynein subunit varies among species: 128 kDa for sea urchin IC1, 75 kDa for Ciona IC3 and 67 kDa for human NM23-H8 protein [114].

The reactive oxygen species are generated in plants as a normal metabolic outcome and is controlled by proline, ascorbate peroxidase (APX), glutathione-S-transferase (GST), thioredoxin h-type, nucleoside diphosphate kinase 1 (NDPK1), superoxide dismutase (SOD), etc. Two week old rice leaves were subjected to glyphosate and reactive oxygen species (ROS) inducing herbicide paraquat. Metal chelation by glyphosate was reported to cause deprivation of co-factors needed for synthesis of antioxidant enzymes SOD, CAT and POX, leading to oxidative stress due to accumulation of ROS. Reduction in RuBisCO large subunit possibly due to protein synthesis inhibition due to accumulation of ROS was also studied (Ahsan et al., 2008).

Another protein included in the function of xenobiotics biodegradation and metabolism was the nucleoside diphosphate kinase 2. The increase in the expression of a similar protein, NDPK-3, being documented in the literature in Arabidopsis thaliana plants, subjected to stress conditions to the PAH phenanthrene, acting in the regulation and signaling of stress metabolisms in plants, where its overexpression increases the activity of several proteins associated with oxidative stress. NDPK-2 physically interacts with two MAP kinases, phytochrome A, and the overexpression of NDPK-2 confers increased stress tolerance to reactive oxygen species (ROS) in Arabidopsis thaliana (Liu et al. 2015).
