H2A.Z-dependent regulation of cohesin dynamics on chromosome arms.

abstract：:Two alternative exons, BEK and K-SAM, code for part of the ligand binding site of fibroblast growth factor receptor 2. Splicing of these exons is mutually exclusive, and the choice between them is made in a tissue-specific manner. We identify here pre-mRNA sequences involved in controlling splicing of the K-SAM exon. ...
