MATR3 overexpression promotes Rev activity. A) Quantitative analysis of unspliced HIV-1 RNA levels modulated by transfected MATR3. Unspliced (US) viral RNA expression in 293T cells was assayed after transfection with Flag-MATR3, vHY-IRES-TK, Tat and Rev-EGFP. Unspliced RNA levels were analyzed by quantitative real-time PCR and data normalized to β-mRNA expression. Data are presented as fold change, whereby 293T cells transfected with vHY-IRES-TK and Tat in the absence of Rev were set as 1. The results of three independent experiments are shown ± SD. The increase was significant (p = 0.01931). B) Transfected MATR3 upregulates Rev-dependent Gag translation. Western blot analysis of protein extracts from 293T cells expressing Flag-MATR3, vHY-IRES-TK, Tat and Rev-EGFP. p17* is the product of the truncated gag gene of the vHY-IRES-TKvector. Tubulin is the protein loading control
