The Complex Role of the ZNF224 Transcription Factor in Cancer
Advances in Protein Chemistry and Structural Biology
|February 21, 2017
Summary
Zinc finger protein 224 (ZNF224) acts as both a tumor suppressor and oncogene in human cancers. Its dual role depends on interacting proteins, offering potential therapeutic targets for cancer treatment.
Area of Science:
- Molecular Biology
- Cancer Research
- Genetics
Background:
- ZNF224, a KRAB-ZFPs family member, was identified as a transcriptional repressor.
- It recruits KAP1, PRMT5, and chromatin modifiers for gene silencing.
- Recent studies reveal ZNF224's complex, context-dependent roles in human cancers.
Purpose of the Study:
- To review the literature on ZNF224's dual role in cancer.
- To examine ZNF224's function as a transcription factor and cofactor.
- To explore how protein interactions influence ZNF224's oncogenic or tumor-suppressive behavior.
Main Methods:
- Literature review of ZNF224 research in cancer.
- Analysis of ZNF224's transcriptional regulatory mechanisms.
- Examination of ZNF224's protein-protein interactions and their functional consequences.
Main Results:
- ZNF224 exhibits context-dependent functions, acting as both a tumor suppressor and an oncogene.
- Its activity is modulated by specific protein partners and cellular context.
- ZNF224 can function in transcriptional activation, not solely repression.
Conclusions:
- ZNF224's dual role in cancer is complex and influenced by its interactome.
- Understanding these mechanisms may lead to novel cancer therapeutic strategies.
- Targeting ZNF224 function offers potential for new cancer treatments.

10.2K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

02:23Master Transcription Regulators
8.0K
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

02:39lncRNA - Long Non-coding RNAs
10.1K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

01:31Transducer Mechanism: Nuclear Receptors
4.3K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
