    ..hnRNP-M affects both 5' and 3' alternative splice site choices, and an hnRNP-M mutant lacking the CDC5L/PLRG1 interaction domain is unable to modulate alternative splicing of an adeno-E1A mini-gene substrate. ..

    ..We propose that the ability of HRP59 to regulate the alternative splicing of its own pre-mRNA serves in a negative feedback loop that controls the levels of the HRP59 protein and maintains the homeostasis of the splicing environment. ..
