We observed a number of factors in the innate response that have been shown to play important roles for the viral infection of the target cell, factors that are involved in HIV-1 endocytosis, nuclear import, integration, transcription, nuclear export and inhibition of antiviral factors (e.g. AGFG1, AP2B1, CUL5, HIVEP1, IPO7, KPNA1, KPNA5, KPNA6, KPNB1, PML, SMAD3, SMAD4, SP1, SUPT4H1, TAF8, TOP1, XRCC6). The gene discussed is KPNA1; the disease is viral infectious disease.
