Figure 6From: Heat shock factor binding in Alu repeats expands its involvement in stress through an antisense mechanism Presence of Alus containing HSF sites in 5-kb proximal regions of antisense signals. HSF sites are especially enriched in the upstream (approximately 2-kb) region of the antisense transcript signal. Antisense transcripts may be transcribed through HSF binding to Alu repeats, leading to down-regulation of sense transcripts in response to heat shock.Back to article page
