RNA splicing mediated by YB-1 is inhibited by TLS/CHOP in human myxoid liposarcoma cells..     ///    The liposarcoma fusion protein TLS/CHOP retains the ability to bind RNA Pol II but lacks the ability to recruit YB-1 due to replacement of the C-terminal domain of TLS by CHOP.     ///    The oncogenic TLS/CHOP fusion protein inhibits this splicing function of YB-1 in a dominant negative manner.
