  • 产品描述：

    CDK4 is a serine/threonine kinase that regulates the orderly progression of the cell cycle by binding to CDK6 and cyclin D and phosphorylating RB to promote the progression through the G1/2 transition. CDK4 and CDK6 contribute to driving the transition from the G1 to S phase during the cell cycle, which is important for mammalian cell proliferation. It is often activated in human cancers and has been regarded as an attractive target for new treatments. CDK4/6 inhibitors such as palbociclib, ribociclib, and abemaciclib block the activation of CDK4/6, leading to cell cycle arrest at the G1 phase.

    Compared with the polyclonal and monoclonal antibodies of CDK4, this CDK4 recombinant antibody has the features of increased reproducibility and control, animal-free technology, high degree of monovalency, high batch-to-batch consistency, easier isotype conversion, etc. And it has been validated in ELISA, WB, IP.

  • 功能：
    Ser/Thr-kinase component of cyclin D-CDK4 (DC) complexes that phosphorylate and inhibit members of the retinoblastoma (RB) protein family including RB1 and regulate the cell-cycle during G(1)/S transition. Phosphorylation of RB1 allows dissociation of the transcription factor E2F from the RB/E2F complexes and the subsequent transcription of E2F target genes which are responsible for the progression through the G(1) phase. Hypophosphorylates RB1 in early G(1) phase. Cyclin D-CDK4 complexes are major integrators of various mitogenenic and antimitogenic signals. Also phosphorylates SMAD3 in a cell-cycle-dependent manner and represses its transcriptional activity. Component of the ternary complex, cyclin D/CDK4/CDKN1B, required for nuclear translocation and activity of the cyclin D-CDK4 complex.
