Synonym	CCNE
Background	Cyclin E1 is a member of the highly conserved cyclin family and belongs to the E-type cyclin that functions as a regulator of S phase entry and progression in mammalian cells. Cyclin E1 serves as regulatory subunits that bind, activate, and provide substrate for its associated cyclin-dependent kinase2 (CDK2), whose activity is essential for cell cycle G1 / S transition. Over expression of this encoding gene has been found in many tumors, which results in chromosome instability and by extension, induce tumorigenesis. This protein was also found to associate with, and be involved in, the phosphorylation of NPAT protein (nuclear protein mapped to the ATM locus), which participates in cell-cycle regulated histone gene expression and plays a critical role in promoting cell-cycle progression in the absence of pRB. In general, cyclin E1, as an activator of phospho-CDK2 (pCDK2), is important for cell cycle progression and is frequently overexpressed in cancer cells.
Description	A DNA sequence encoding the human CCNE1 (NP_001229.1) (Met 1-Ala 410) was expressed and purified with two additional amino acids (Gly & Pro ) at the N-terminus.
Source	Baculovirus-Insect Cells
Predicted N Terminal	Gly
AA Sequence	Met 1-Ala 410
Molecular Weight	The secreted recombinant human CCNE1 consists of 412 a.a. and predicts a molecular mass of 47.2 KDa. The apparent molecular mass of the protein is approximately 48 KDa in SDS-PAGE under reducing conditions due to glycosylation.
Purity	>90% as determined by SDS-PAGE
Endotoxin	< 1.0 EU per μg of the protein as determined by the LAL method
Bioactivity	Measured by its binding ability in a functional ELISA. Immobilized human CCNE1 at 10 ug/ml (100 ul/well) can bind biotinylated human GST-CDK4, The EC50 of biotinylated human GST-CDK4 is 0.55-1.29 ug/ml.
Formulation	Lyophilized from sterile 20mM Tris, 500mM NaCl, 10% glycerol, pH 7.4..
Stability	The recombinant proteins are stable for up to 1 year from date of receipt at -70°C.
Usage	For Research Use Only
Storage	Store the protein under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
