RNA antisnse puriification of Tau exon 10 pre-mRNA


ABSTRACT: In this study, we demonstrated the use of the RNA Antisense Purification by Mass Spectrometry (RAP-MS) method to identify proteins involved in specific alternative splicing events. Specifically, we applied the RAP-MS method to identify proteins that interact with the Tau pre-mRNA around its exon 10 region.

Alternative splicing in Tau exon 10 generates 3 R- and 4 R-Tau proteoforms, which have equal abundance in healthy adult human brain. Aberrant alternative splicing in Tau exon 10 leads to distortion of the balanced 3 R- and 4 R-Tau expression levels, which is a causal factor to trigger toxic Tau aggregation, neuron dysfunction and patient death in a group of neurodegenerative diseases known as tauopathies. Hence, identification of regulators upstream of the Tau exon 10 splicing events are crucial  ...[more]
