Does not support changes in cardiomyopathy care; hypothesis-generating for MLP cytoskeletal mechanisms in mammals.
Mlp84B and alpha-actinin function synergistically to stabilize muscle cytoarchitecture via actin cross-linking, suggesting a mechanism for MLP-associated cardiomyopathies.
Clark et al. (2013) studied MLP-associated cardiomyopathies. Mlp84B and α-actinin RNAi knockdown vs. Single-gene RNAi or traditional loss-of-function alleles was evaluated on Lethality and Z-line structure destabilization. Simultaneous RNAi knockdown of Mlp84B and α-actinin in Drosophila produced synergistic early larval lethality and destabilization of Z-line structures, indicating overlapping functions.
