RFX1 binds and regulates the enhancers of a number of viruses and cellular genes. RFX1 belongs to the evolutionarily conserved RFX protein family that shares a DNA-binding domain and a conserved C-terminal region. In RFX1 this conserved region mediates dimerization, and is followed by a unique C-terminal tail, containing a highly acidic stretch. In HL-60 cells nuclear translocation of RFX1 is regulated by protein kinase C with unknown mechanisms. By confocal fluorescence microscopy, we have…

Sequence Properties of an Intramolecular Interaction that Inhibits p53 DNA Binding

It is shown that the ND mutants have similar Stokes radii to ND WT suggesting the mutants disrupt autoinhibition without changing the global structure, indicating there is some cooperation between acidic, nonpolar, and aromatic residues from TAD2 to inhibit DNA binding.

RFX1 Mediates the Serum-induced Immediate Early Response of Id2 Gene Expression*

RFX1 mediates the immediate early response of the Id2 gene by serum stimulation and suggest that the function of RFX1 is regulated intramolecularly in its suppression in growth-arrested cells.

RFX-1-dependent activation of SHP-1 inhibits STAT3 signaling in hepatocellular carcinoma cells.

It is confirmed that RFX-1 acts as a tumor suppressor in HCC and might be a new target for HCC therapy and provide a new lead compound for targeted therapy via the activation of the R FX-1/SHP-1 pathway.

Autorepression of Rfx1 Gene Expression: Functional Conservation from Yeast to Humans in Response to DNA Replication Arrest

It is suggested that Rfx1 plays a role in the DNA damage response by down-regulating a subset of genes whose expression is increased in response to replication blocking and UV-induced DNA damage.

Regulation of FGF1 Gene Promoter through Transcription Factor RFX1*

Evidence is presented that transcription factor RFX1 could bind the 18-bp cis-elements of the F1B promoter, modulate F1BGFP expression and endogenous FGF1 expression, and further regulate the maintenance of GBM-SCs.

RFX1: a promising therapeutic arsenal against cancer

This review discusses the pleiotropic function of RFX1 in multitudinous gene regulations, decisive protein–protein interactions, and also its role in regulating key cell signaling events in cancer.



RFX1, a Single DNA-binding Protein with a Split Dimerization Domain, Generates Alternative Complexes*

The results propose a mechanism by which the extended dimerization domain mediates the formation of alternative homodimeric complexes, which differ in the nature of the intersubunit interaction, thus affecting transcriptional activity.

The transcriptional activation and repression domains of RFX1, a context-dependent regulator, can mutually neutralize their activities.

It is proposed that relief of self-neutralization may allow RFX1 to act as a dual-function regulator via its activation and repression domains, accounting for the context-dependent activity of EP.

The dimerization/repression domain of RFX1 is related to a conserved region of its yeast homologues Crt1 and Sak1: a new function for an ancient motif.

A comparative analysis of the RFX proteins, representing different evolutionary stages, suggests a gradual development of the conserved C terminus, from the appearance of the ancestral motif (Crt1), to the later acquisition of the dimerization/repression functions (Sak1), and finally to the enhancement of these functions to generate a domain mediating highly stable protein-protein interactions and potent transcriptional repression (RFX1).

RFX proteins, a novel family of DNA binding proteins conserved in the eukaryotic kingdom.

Until recently, the RFX family of DNA binding proteins consisted exclusively of four mammalian members (RFX1-RFX4) characterized by a novel highly conserved DNA binding domain. Strong conservation of

Dimeric RFX Proteins Contribute to the Activity and Lineage Specificity of the Interleukin-5 Receptor α Promoter through Activation and Repression Domains

The findings suggest that RFX proteins are transcription factors that contribute to the activity and lineage specificity of the IL-5Rα promoter by directly binding to a target cis element and cooperating with other tissue- and lineage-specific cofactors.

RFX1, a transactivator of hepatitis B virus enhancer I, belongs to a novel family of homodimeric and heterodimeric DNA-binding proteins.

It is shown here that RFX1 belongs to a previously unidentified family of DNA-binding proteins of which three members are cloned from humans and mice, and members of the RFX family constitute the nuclear complexes that have been referred to previously as enhancer factor C, EP, methylation-dependent DNA- binding protein, or rpL30 alpha.

The kinase activity of c-Abl but not v-Abl is potentiated by direct interaction with RFXI, a protein that binds the enhancers of several viruses and cell-cycle regulated genes

A novel mechanism of c-Abl recruitment to a defined DNA-cis element with its concomitant kinase activation is described and it is proposed that this mechanism may act to regulate cell-cycle control genes.

Regulation of protein transport to the nucleus: central role of phosphorylation.

Results indicate that NLS-dependent nuclear protein import is precisely regulated, and the CcN motif appears to be a special form of phosphorylation-regulated NLS (prNLS), where phosphorylated at site(s) close to the NLS specifically regulates NLS function.

Interaction of EF-C/RFX-1 with the Inverted Repeat of Viral Enhancer Regions Is Required for Transactivation (*)

The results suggest that an additional activity may be required to stabilize EF-C/RFX-1 interaction with the MHC class II promoter, and that viral enhancer regions have evolved high affinity binding sites to sequester dimeric EF- C/R FX-1.

Involvement of RFX1 Protein in the Regulation of the Human Proliferating Cell Nuclear Antigen Promoter*

It is suggested that the binding of RFX1 is influenced by sequences outside its consensus binding site and that this transcription factor plays an inhibitory role in the regulation of PCNA gene expression.
