Description

Mouse Monoclonal Antibody

The monoclonal antibody HE12 recognizes human Cyclin E. Cyclins regulate the cell cycle by binding and activating cyclin-dependent kinases (CDK). Cyclin E regulates the transition from G1 to S phase by binding and activating CDK2. The Cyclin E/CDK2 complex is responsible for the phosphorylation of downstream proteins that facilitate the G1 to S phase transition. Overexpression of Cyclin E is found in several types of cancer including breast, colon, bladder, lung and skin. In breast cancer, Cyclin E overexpression is associated with increased stage and grade as well as poor prognosis. Applications Reported: This HE12 antibody has been reported for use in immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, microscopy, and immunocytochemistry. Applications Tested: This HE12 antibody has been tested by immunohistochemistry of FFPE human tissue using low pH antigen retrieval and can be used at less than or equal to 10 μg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Filtration: 0.2 μm post-manufacturing filtered.

Cyclin E belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. Cyclin E forms a complex with and functions as a regulatory subunit of CDK2, whose activity is required for cell cycle G1/S transition. This protein accumulates at the G1-S phase boundary and is degraded as cells progress through S phase. Overexpression of this gene has been observed in many tumors, which results in chromosome instability, and thus may contribute to tumorigenesis. This protein was 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. Two alternatively spliced transcript variants of this gene, which encode distinct isoforms, have been described. Two additional splice variants were reported but detailed nucleotide sequence information is not yet available.
