ORC is required to assemble the pre-replication complex necessary to initiate DNA replication (436 aa) | |||
DBF4 | DBF4 homolog (S. cerevisiae); Regulatory subunit for CDC7 which activates its kinase activity thereby playing a central role in DNA replication and cell proliferation. Required for progression of S phase. The complex CDC7-DBF4A selectively phosphorylates MCM2 subunit at ’Ser-40’ and ’Ser-53’ and then is involved in regulating the initiation of DNA replication during cell cycle (674 aa) | |||
RB1 | retinoblastoma 1; Key regulator of entry into cell division that acts as a tumor suppressor. Promotes G0-G1 transition when phosphorylated by CDK3/cyclin-C. Acts as a transcription repressor of E2F1 target genes. The underphosphorylated, active form of RB1 interacts with E2F1 and represses its transcription activity, leading to cell cycle arrest.
