You will need a ride home after the procedure because of the medicines or anesthesia you received. Coronary angiography is a common procedure that rarely causes serious problems. Possible complications may include bleeding, allergic reactions to the contrast dye, infection, blood vessel damage, arrhythmias, blood clots that can trigger a heart attack or stroke, kidney damage, and fluid buildup around the heart.
(Redirected from Corepressor (genetics)) In the field of molecular biology, a corepressor is a substance that inhibits the expression of genes. In prokaryotes, corepressors are small molecules whereas in eukaryotes, corepressors are proteins. A corepressor does not directly bind to DNA, but instead indirectly regulates gene expression by binding to repressors.
In eukaryotes, a corepressor is a protein that binds to transcription factors. In the absence of corepressors and in the presence of coactivators, transcription factors upregulate gene expression. Coactivators and corepressors compete for the same binding sites on transcription factors.
