Biological background
Protein function (datasheet): CDKN1B: Important regulator of cell cycle progression. Involvedin G1 arrest. Potent inhibitor of cyclin E- and cyclin A-CDK2complexes. Forms a complex with cyclin type D-CDK4 complexes andis involved in the assembly, stability, and modulation of CCND1-CDK4 complex activation. Acts either as an inhibitor or anactivator of cyclin type D-CDK4 complexes depending on itsphosphorylation state and/or stoichometry.
Scientific background (datasheet): P27 (kip1), also known as cyclin dependent kinase inhibitor 1B (CDKN1B), is a major target of AFX-like forkhead proteins. CDKN1B (p27) belongs to the Cip/Kip family and functions as an important cell cycle gatekeeper. Phosphorylation leads to the ubiquitination and degradation of CDKN1B. P27 (kip1) mapped to 12p13. An increase in p27 causes proliferating cells to exit from the cell cycle, and a decrease in p27 is necessary for quiescent cells to resume division. Abnormally low amounts of p27 are associated with pathological states of excessive cell proliferation, especially cancers. Overexpression of p27Kip1 lengthens the G1 phase in a mouse model that targets inducible gene expression to central nervous system progenitor cells.
Cellular localization (datasheet): CDKN1B: Nucleus. Cytoplasm. Endosome Note: Nuclear and cytoplasmic in quiescent cells. AKT- or RSK-mediated phosphorylation on Thr-198, binds 14-3-3, translocates tothe cytoplasm and promotes cell cycle progression. Mitogen-activated UHMK1 phosphorylation on Ser-10 also results intranslocation to the cytoplasm and cell cycle progression.Phosphorylation on Ser-10 facilitates nuclear export. Translocatesto the nucleus on phosphorylation of Tyr-88 and Tyr-89.Colocalizes at the endosome with SNX6; this leads to lysosomaldegradation (By similarity). |Cdkn1b: Nucleus. Cytoplasm. Endosome.

Research relevance and current trends
- Commonly studied in contexts related to Cancer,Cell Biology,Cell Cycle,Cell Cycle Inhibitors,Epigenetics and Nuclear Signaling.
- Supports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.
- Useful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).
Common research applications
- Western blot (WB): Compare relative target abundance and apparent size/isoforms across samples; interpret bands in light of expected MW and potential PTMs.
- Immunofluorescence / ICC: Visualize subcellular localization and co-localization patterns; consider fixation/permeabilization compatibility and controls.
Notes for experimental interpretation
- Consider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.
- Cross-reactivity (datasheet): No cross-reactivity with other proteins
- Use appropriate positive and negative controls (e.g., KO/KD, blocking peptide, or isotype controls) to support specificity interpretation.
As a monoclonal antibody, this reagent is expected to recognize a defined epitope, which can support consistency across lots when epitope accessibility is preserved.
