- 产品介绍
- background:
E4F1, also known as E4F, is a 784 amino acid protein that localizes to both the nucleus and the cytoplasm and contains nine C2H2-type zinc fingers. Expressed ubiquitously in adult and fetal tissues, E4F1 exists as a homodimer that binds DNA and is thought to act as a transcriptional repressor and may also play a role in cell survival and growth via cell cycle control. Additionally, E4F1 is thought to function as a ubiquitin ligase that mediates the ubiquitination (and subsequent degradation) of target proteins and may be involved in the p53 tumor suppressor pathway. E4F1, which may be post-translationally phosphorylated or sumoylated, is subject to proteolytic cleavage which results in the creation of a short peptide with specific DNA binding capabilities.
Function:
May function as a transcriptional repressor. May also function as a ubiquitin ligase mediating ubiquitination of chromatin-associated TP53. Functions in cell survival and proliferation through control of the cell cycle. Functions in the p53 and pRB tumor suppressor pathways and regulates the cyclin CCNA2 transcription. [FUNCTION] Identified as a cellular target of the adenoviral oncoprotein E1A, it is required for both transcriptional activation and
Subunit:
Homodimer; binds DNA as a dimer. Forms a complex with CDKN2A and TP53. Interactions with TP53, RB1, ANP32A, BMI1 and FHL2 regulate E4F1 activity. Interacts with HDAC1, HMGA2 and RASSF1. Interacts with HBV protein X.
Subcellular Location:
Nucleus, nucleoplasm. Cytoplasm. Note=A small fraction is detected in the cytoplasm. Excluded from the nucleolus where it is targeted upon CDKN2A overexpression. Localizes to the mitotic spindle during embryogenesis (By similarity).
Tissue Specificity:
Ubiquitously expressed.
Post-translational modifications:
Proteolytic cleavage produces a 50 kDa N-terminal peptide (p50E4F) which has a DNA-binding activity and activates transcription in presence of the adenoviral E1A protein. The major full length protein (p120E4F) functions as a repressor of transcription.
Phosphorylated; p120E4F and p50E4F are both phosphorylated. Phosphorylation is cell cycle-dependent and differentially regulates DNA-binding activity and function of both forms.
May be sumoylated by UBE2I upon interaction with CDKN2A.
Similarity:
Contains 9 C2H2-type zinc fingers.
