Protein Target Info (Source:

Uniprot Id O08769
Gene Name CDKN1B
Protein Name cyclin-dependent kinase inhibitor 1B(p27, Kip1)
Tissue Specificity CDKN1B: Expressed in all tissues tested. Highestlevels in skeletal muscle, lowest in liver and kidney.
Alternative Names Cyclin dependent kinase inhibitor ;Cyclin kinase inhibitor ;Cyclin-dependent kinase inhibitor 1B ;P27 kip1 ;P27kip1 ;Protein Cdkn1b ;Cdkn1b ;p27Kip1 ;rCG_29991 ;
Subcellular Localization 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.

Protein Function 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.

Background 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.
