  Function in Host
Enhances the ATPase activity of DHX15 by acting like a bracethat tethers mobile sections of DHX15 together, stabilizing afunctional conformation with high RNA affinity of DHX15. Involved in the constitutive silencing of theinterferon beta promoter, independently of the virus-induced signals, and in the inhibition of the basal and cytokine-induced iNOS promoteractivity. Also involved in the regulation of IL-8transcription. May also act as a DNA-bindingtranscription regulator: interacts with a specific negative regulatoryelement (NRE) 5'-AATTCCTCTGA-3' to mediate transcriptional repressionof certain NK-kappa-B responsive genes.
