Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu405 of human E2F4 protein.

Background

The E2F family consists of 8 transcription factors that regulate genes that control cell cycle progression by complexing with DP and Rb proteins (1-4). E2F transcriptional activation is generally opposed by associating with RB proteins, pRB, p107, and p130 (5-7). E2F-1, -2, and -3a function as activators that can help quiescent cells enter S phase, while E2F-3b, -4, and -5 repress cell growth through the recruitment of HDAC’s and other corepressors to target genes (8-10). E2F-6 diverges considerably from other family members, and has repressive properties governed not through interaction with Rb proteins, but by recruiting the polycomb repressive complex (11,12). E2F-7, and -8 are unique in that they have two DNA-binding domains and do not heterodimerize with DP proteins. These E2F family members repress transcription and delay progression of the cell cycle through the regulation of E2F-1 (13-15)
