The DEAD-box p68/p72 proteins and the noncoding RNA steroid receptor activator SRA: eclectic regulators of disparate biological functions.

p68 and p72 are RNA-binding proteins endowed with RNA helicase and RNA-protein complex remodeling activities. One of the RNAs associated with p68/p72 is the noncoding Steroid Receptors RNA Activator (SRA). Here we review recent findings on the cellular processes regulated by either p68/p72 alone or in combination with SRA and discuss the transcriptional events influenced by these molecules.
