Figure Lengend Snippet: Th-T based aggregation kinetics of 25 μM αSyn 1–103 in the presence of 25 μM representative proteins from each group: LB components (PIN1, LH1.5_GD), known interactors (BSA, lysozyme, SIRT6, and Fyn-SH3 domain), and uncharacterized binders (RNase, TEV protease, GST, and PSIP1-PWWP domain). Controls include αSyn 1–103 alone (red) and individual proteins alone (yellow). Data represent the mean of three individual triplicates ( n = 3) and the error bar shows ±SD. Representative T₅₀ values, derived from one-phase exponential association kinetics, for αSyn 1–103 control and its 1:1 mixtures with cellular proteins are presented as a comparative bar graph. The dashed line indicates the T₅₀ value for the αSyn 1–103 control.

Article Snippet: Pin1 FL (#40773), Tau FL (#16316), and PSIP1-PWWP (1-135) domain (#40744) constructs were obtained from Addgene. (His) 6 -tagged proteins (Pin1 and PSIP1-PWWP domain) were expressed in E. coli BL21(DE3) using 0.5 mM IPTG induction at 37°C for 6 h and purified initially using Ni 2+ -affinity chromatography (HiTrap IMAC FF, Cytiva).

Figure Lengend Snippet: Fig. 6 Silencing PSIP1 inhibited proliferation, invasion and migration of OS. (A-B) CCK8 (A) and colonies plate information assays (B) were used to mea sure the effects of silencing or up-regulating PSIP1 in OS cells. (C) Transwell migration assays were used to detect the migratory ability of OS cells with silencing or up-regulating PSIP1. (D) The subcutaneous tumor morphology after knockdown of PSIP1. (E-F) The size (E) and weight (F) of tumors. (G) The HE results and IHC results of PSIP1 and Ki-67 of subcutaneous tumors
