  • 产品描述：

    This is a CDKN1B recombinant monoclonal antibody produced in vitro expression system. The clones constructed by the human CDKN1B DNA gene and vector were transfected into the cell line for production. This CDKN1B antibody is purified using affinity-chromatography. It can recognize the CDKN1B protein of human- and mouse-origin. It is recommended for applications, including ELISA, WB, IHC, and IF.

    CDKN1B, also called p27kip1, is a cyclin-dependent kinase inhibitor involved in the G1–S transition. Cytoplasmic p27kip1 participates in cellular processes including cytoskeleton dynamics, cell migration, and metastasis and plays a role in tumor development and disease progression.

  • 功能：
    Important regulator of cell cycle progression. Inhibits the kinase activity of CDK2 bound to cyclin A, but has little inhibitory activity on CDK2 bound to SPDYA. Involved in G1 arrest. Potent inhibitor of cyclin E- and cyclin A-CDK2 complexes. Forms a complex with cyclin type D-CDK4 complexes and is involved in the assembly, stability, and modulation of CCND1-CDK4 complex activation. Acts either as an inhibitor or an activator of cyclin type D-CDK4 complexes depending on its phosphorylation state and/or stoichometry.
