“…Mutant HTT affects the expression of actin-related proteins (Ratovitski et al, 2016). One study implicated HTT in actin dynamics: by binding to the methyltransferase SETD2, HTT enhances actin methylation and polymerization in HEK cells (Seervai et al, 2020). Here we provide the evidence that HTT influences actin cytoskeletal dynamics in dendritic spines.…”
