    ..However, CF I(m)68 does not concentrate in splicing speckles but in foci that partially colocalize with paraspeckles, a subnuclear component in which other proteins involved in transcriptional control and RNA processing have been found. ..

    ..Thus, this study establishes that CFIm not only plays a general role in 3'-end processing but also plays a regulatory role in poly(A) site selection. ..

    ..The intrinsic ability of CFI(m) to direct RNA looping may provide a mechanism for its function in the regulation of alternative poly(A) site selection. ..
