"Study showed that TNFRSF19 is highly expressed in nasopharyngeal carcinoma (NPC) and is required for cell proliferation and NPC development. TNFRSF19 was not involved in NFkappaB activation or associated with TRAF proteins. TbetaRI was identified as a specific binding partner for TNFRSF19. TNFRSF19 bound the kinase domain of TbetaRI in the cytoplasm thereby blocking Smad2/3 association with TbetaRI and subsequent sign..."xsd:string
