چکیده انگلیسی
Major histocompatibility complexes class II are responsible for the antigen presentation that shapes the repertoire of the adaptive immune responses. All members of the MHCII family of genes are controlled by the same set of conserved transcription factors and promoter elements, resulting in coordinated transcription. We report the role of a previously unidentified AT-hook motif of the MHCII regulatory factor RFX5, and show that this is involved in regulating the transcription of the HLA-DQ, but not HLA-DR, MHCII isotype. Furthermore, PRMT6, an arginine methyltransferase known to methylate AT-hook motifs, downregulates the expression of HLA-DQ, but not HLA-DR, in an AT-hook-dependent manner. This can provide a fine-tuning mechanism for isotype-specific transcriptional regulation, where a post-translational modification modulates the relative levels of the MHCII isotypes.
