Gene Information

human ... E2F1(1869)

General description

E2F-1 was identified as a cellular protein with DNA binding activity associated with the adenovirus E2 gene promoter. The original member of the E2F family of transcription factors, now consisting of five, was identified through its association with the retinoblastoma protein, which controls its activity. E2F-1 is cell cycle regulated with very low levels in early G1 then increasing levels as cells move from G1 to S with highest levels of protein at the G1/S boundary, which is consistent with its role in S-phase entry.

Specificity

Recognizes E2F-1.

Immunogen

Epitope: The epitope for KH20 has been mapped to amino acids 1-89; KH95 to amino acids 342-386.
GST fusion protein corresponding to full-length human E2F-1.

Application

Anti-E2F-1 Antibody, clones KH20 & KH95 is a high quality Mouse Monoclonal Antibody for the detection of E2F-1 & has been validated in IP & WB.

Quality

Immunoblot Analysis: 0.5-2μg/ml of this antibody detected E2F-1 in a HeLa nuclear extract.
Immunoprecipitation: 4μg of this antibody immunoprecipitated E2F-1 from HeLa nuclear extract.
Gel Shift: The KH20 clone has been shown to gel shift the E2F-1/DP-1/DNA complex (Helin, 1993; Wu, 2000).
