The application discloses application of TRIM11
protein in preparation of a
medicine for treating
spinocerebellar ataxia 51. The application adopts an SCA51 specific
cell model, and identifies, through a large number of screening experiments, that the TRIM11
protein has the function of significantly removing
mutant THAP11
protein and aggregates thereof. Experimental data show that the
mutant protein removal efficiency of the TRIM11 treatment group is significantly better than that of the control group. The application verifies the removal effect of TRIM11 on the SCA51
pathological protein from the two dimensions of
protein expression level and
subcellular localization through Western blotting quantitative analysis and
immunofluorescence co-localization technology. The three-dimensional reconstruction image clearly shows that the
mutant protein aggregates are significantly reduced. The application first establishes a complete
research system from target discovery to
mechanism analysis, and provides a new intervention strategy for precise treatment of SCA51.
