Cdk7 phase separation
WebScale bar: 10 μm. (E and F) After nuclear and cytoplasmic extraction, the expression of MAT1 and CDK7 in G1 and S phase of cells infected with CVB3 or transfected with pBud-VP1 plasmid were detected. WebCDK7 has been observed as a prerequisite to S phase entry and mitosis. CDK7 is activated by the binding of cyclin H and its substrate specificity is altered by the binding of MAT1. …
