Cells were fixed in 4% Paraformaldehyde and permeabilized with 0.1% tritonX-100. Cells were counterstained with ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) 1 : 200 (2.5 µg/ml). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) was used as the secondary antibody at 1 : 1000 (2 µg/ml) dilution. DAPI (blue) was used as nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

Supplementary information

The EWS protein also known as EWSR1 or 2'1b1' comes from the EWSR1 gene. It is a part of the TET family of proteins and has a molecular weight of about 68 kDa. EWS is expressed widely in human tissues with high levels in the brain gonads and skeletal muscle. The protein contains an RNA-binding domain and amino acid repeats which allow it to interact with other proteins and RNA molecules.
Biological function summary

The EWS protein plays roles in various cellular processes such as transcription and RNA splicing. It can participate in forming different protein complexes which influence its function. EWS serves as a cofactor for several transcription factors and it is important in regulating the expression of genes involved in cell cycle progression and differentiation. The protein’s interaction with RNA and other molecules highlights its multifunctional nature within cellular environments.

Pathways

EWS engages in pathways like the regulation of transcription and RNA processing. It closely associates with proteins involved in gene expression surveillance such as the RNA polymerase II which is significant for transcription activities. EWS partners with proteins such as FUS and TAF15 which are essential parts of transcription regulation networks. These interactions place EWS in a central role in cellular regulatory machinery.

EWS is notably linked to Ewing sarcoma and neurodegenerative diseases. In Ewing sarcoma EWS forms fusion proteins like EWS-FLI1 by translocation events which lead to tumor formation. This fusion protein acts abnormally in transcription regulation driving oncogenic pathways. EWS's interaction with proteins like FUS and TAF15 also relate it to certain neurodegenerative conditions indicating its importance in both cancer and neurobiology.

Target data

Might normally function as a transcriptional repressor. EWS-fusion-proteins (EFPS) may play a role in the tumorigenic process. They may disturb gene expression by mimicking, or interfering with the normal function of CTD-POLII within the transcription initiation complex. They may also contribute to an aberrant activation of the fusion protein target genes.
