CCNT1 and infection: A variety of well-documented cellular cofactors for infection were identified in two out of three screens, including i) the binding and entry factors CD4 and CXCR4; ii) the NFkappaB subunit RELA; iii) the activating kinases AKT1 and JAK1; iv) the Vpr and Vif cofactor TCEB3/elonginB; and v) the Tat cofactor CCNT1/cyclinT1 [16] (which was also in the mass spectrometry study of Tat-associated proteins).
