Anti- p27Kip1 (Ab-10) Antibody Antibody (GWB-37FF7C)



Add to Cart


Binding Site: around Ser10

Form of Antibody: Rabbit IgG in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol

Immunogen: The antiserum was produced against syntheseized non-phosphopeptide derived from human p27Kip1 around the phosphorylation site of serine 10 (N-G-Sp-P-S).

Purification: The antibody was affinity-chromatography using epitope-specific immunogen. WB Dilution: 500~1000

IHC Dilution: 50~100 Specificity/Sensitivity: p27Kip1 (Ab-10) antibody detects endogenous levels of total p27Kip1 protein. Function: Involved in G1 arrest. May mediate TGF beta-induced G1 arrest. Binds to and inhibits complexes formed by cyclin E-CDK2, cyclin A-CDK2, and cyclin D1-CDK4. Interaction with nucleoporin NUP50 is required for nuclear import and for degradation of phosphorylated p27Kip1 after nuclear import (By similarity).

Subunit: Interacts with NUP50 and with UHMK1. Interacts with COPS5 subunit of COP9 signalosome complex, leading to its subsequent degradation (By similarity). Interacts with SPDYA and is found in a complex with both SPDYA and CDK2.

Subcellular Location: Nucleus (By similarity). Cytoplasm (By similarity). Note=Nuclear and cytoplasmic in quiescent cells. Upon cell cycle progression, mostly cytoplasmic (By similarity).

Tissue Specificity: Expressed in all tissues tested. Highest levels in skeletal muscle, lowest in liver and kidney.

Domain: A peptide sequence containing only AA 28-79 retains substantial KIP1 cyclin A/CDK2 inhibitory activity.

Ptm: Phosphorylation on Ser-10 leads to nuclear export to the cytoplasm and promotes cell cycle progression (By similarity). Phosphorylated upon DNA damage, probably by ATM or ATR.

Disease: Defects in CDKN1B are the cause of multiple endocrine neoplasia type 4 (MEN4) [MIM:610755]. Multiple endocrine neoplasia (MEN) syndromes are inherited cancer syndromes of the thyroid. MEN4 is a MEN-like syndrome with a phenotypic overlap of both MEN1 and MEN2.

Similarity: Belongs to the CDI family. [1] Polyak K., Lee M.-H., Erdjument-Bromage H., Koff A., Roberts J.M., Tempst P., Massague J.
