WebJun 25, 2024 · Cyclins are a group of related proteins, and there are four basic types found in humans and most other eukaryotes: • G1 Cyclins,G1/S cyclins, S cyclins, and M cyclins. ... a growth factor receptor may send signals even when growth factors are not there, or a cyclin may be expressed at abnormally high levels. • The overactive (cancer ... WebMar 28, 2024 · A novel 761-amino-acid transcription factor, DMP1, ... Taken together, these findings suggest that DMP1 induces genes that inhibit S phase entry and that D-type cyclins can override DMP1-mediated growth arrest in a CDK-independent manner.
