Anti-E2F-7 Antibody, clone 14C3.2

Transcription factor E2F7 (UniProt Q96AV8; also known as E2F-7) is encoded by the E2F7 gene (Gene ID 144455) in human. The E2F family of transcription factors (E2F) regulate genes involved in cell proliferation, differentiation and apoptosis. E2F1, 2, 3a function as transcription activators, while other family members (E2F3b, 4, 5, 6, 7, 8) are known as transcription repressors. Upregulated E2F7 is found in tamoxifen-resistant breast cancer cells, where it is responsible for transcriptional repression of miR-15a/16. Exogenous expression of miR-15a/16 or silencing E2F7 re-sensitizes breast cancer cells to tamoxifen-induced cell cycle arrest and apoptosis. Upregulated E2F7 expression is also reported in cutaneous squamous cell carcinomas (CSCC) and and head and neck SCC (HNSCC), where E2F7-dependent Sphk1 overexpression in SCC results in an elevated production of the antiapoptotic phospholipid, sphingosine-1-phosphate (S1P), which in turn invokes anthracycline resistance via activation of the PI3K/AKT pathway.

Clone 14C3.2 recognizes an internal epitope of human E2F-7 present in all three spliced isoforms reported by UniProt (Q96AV8).

Epitope: Internal (C-terminal half).

GST-tagged recombinant human E2F-7 internal fragment.

Immunocytochemistry Analysis: A 1:250 dilution from a representative lot detected E2F-7 in A431, HeLa, HepG2 and NIH/3T3 cells.
