Zinc finger protein 238 (also known as RP58 or ZBTB18) is a zinc finger containing transcription factor that in humans is encoded by the ZNF238 gene. [5] [6]

Contents

Function

ZNF238 is a gene that plays a major role in the "promotion of ordered and correctly timed neurogenesis leading to proper layer formation and cortical growth." [7] The loss of ZNF238 has been observed to cause microcephaly, agenesis of the corpus callosum, malformation of layers in the cerebral cortex, and cerebellar hypoplasia. [7] Additionally, its absence can cause a decrease in Ngn2 and Neurod1 (in progenitor cells, and an increase thereof in mutant neurons), with the result of less progenitor cells and an increase in neuronal differentiation and glial cell growth. [7] ZNF238 also regulates repressed genes that, if left unchecked, can lead to glioma progression. Furthermore, an absence of ZNF238 results in upregulation of the epithelial-mesenchymal transition process.

In tumors such as medulloblastomas, the loss of ZNF238 can disorganize the tumor's cellular divisional processes, resulting in a cellularly diverse neoplasm. This new diversity has been observed to increase the invasiveness of the tumor, yielding proliferation into more areas of the brain than before the loss of ZNF238.

C2H2-type zinc finger proteins, such as ZNF238, act on the molecular level as transcriptional activators or repressors and are involved in chromatin assembly. [8]

Interactions

ZNF238 has been shown to interact with DNMT3A. [9]

RE1-Silencing Transcription factor (REST), also known as Neuron-Restrictive Silencer Factor (NRSF), is a protein which in humans is encoded by the REST gene, and acts as a transcriptional repressor. REST is expressly involved in the repression of neural genes in non-neuronal cells. Many genetic disorders have been tied to alterations in the REST expression pattern, including colon and small-cell lung carcinomas found with truncated versions of REST. In addition to these cancers, defects in REST have also been attributed a role in Huntington Disease, neuroblastomas, and the effects of epileptic seizures and ischemia.

Zinc Finger Protein 548 (ZNF548) is a human protein encoded by the ZNF548 gene which is located on chromosome 19. It is found in the nucleus and is hypothesized to play a role in the regulation of transcription by RNA Polymerase II. It belongs to the Krüppel C2H2-type zinc-finger protein family as it contains many zinc-finger repeats.

ZNF839 or zinc finger protein 839 is a protein which in humans is encoded by the ZNF839 gene. It is located on the long arm of chromosome 14. Zinc finger protein 839 is speculated to play a role in humoral immune response to cancer as a renal carcinoma antigen (NY-REN-50). This is because NY-REN-50 was found to be over expressed in cancer patients, especially those with renal carcinoma. Zinc finger protein 839 also plays a role in transcription regulation by metal-ion binding since it binds to DNA via C2H2-type zinc finger repeats.
