Scientific Background	Human alpha synuclein S87N mutant (HuS87N) has Ser87 mutated to the equivalent mouse residue Asn87, effectively making it a human-mouse chimeric protein. <br /><br />Despite sequence differences at only seven residues, or 5% of the total 140 amino acids, the aggregation rate of wild-type mouse alpha-syn (MsWT) is faster than wild-type human alpha-syn (HuWT) in vitro. In wild-type mouse models, MsWT fibrils are more efficient than HuWT fibrils at inducing endogenous mouse alpha-syn pathology (1). A53T or S87N substitutions in human alpha-syn substantially accelerate fibrilization rates in vitro (2,3).<br />Chimeric HuS87N fibrils show enhanced induction of alpha-syn pathology greater than both HuWT and MsWT fibrils in mice neuron cultures (4). <br /><br />Therefore, HuS87N is a good construct for inducing robust endogenous alpha-syn seeding and pathology in wild-type mice/cultures.
