The present study screened a human fetal brain cDNA library to find the proteins that interact with mutant superoxide dismutase 1 (SOD1) using a yeast two-hybrid system. Using BLAST software, 15 real proteins which interacted with mutant SOD1 were obtained, including 8 known proteins (protein tyrosine-phosphatase non-receptor type 2, TBC1D4, protein kinase family, splicing factor, arginine/serine-rich 2, SRC protein tyrosine kinase Fyn, β-sarcoglycan; glycine receptor α2, micro-tubule associated protein/microtubule affinity-regulating kinase 1, ferritin H chain), and 7 unknown proteins. Results demonstrated interaction of mutant SOD1 with microtubule associated pro-tein/microtubule affinity-regulating kinase 1 and β-sarcoglycan.
