Both DHX36 and DHX9 were found to interact with MyD88 when co-expressed in human embryonic kidney 293T cells. Moreover, the HA2 and DUF domains of DHX were critical for interaction with the TIR domain of MyD88 [Kim T et al 2010].

DHX9 or DHX36 knockdown by siRNA inhibited cytokine release in human GEN2.2 cell line (leukemic pDC cells) in response to CpG-ODN or to HSV but not to RNA viruses. Furthermore, knockdown of DHX36 diminished the nuclear localization of IRF7 in CpG-A-stimulated cells, while knockdown of DHX9 inhibited nuclear localization of NF-kappaB p50 in response to CpG-B. Thus, DHX36 and DHX9 are thought to trigger MyD88-dependent IRF7 and NF-kappaB activation respectively [Kim T et al 2010].
