B-cell CLL/lymphoma
To identify ARX interacting proteins, we performed an unbiased proteomics screen and identified several components of the Wnt/b-catenin signaling pathway, including b-catenin (CTNNB1), B-cell CLL/lymphoma 9 (BCL9) and leucine rich repeat flightless interacting protein 2 (LRRFIP2), in cortical progenitor cells.
