NCIt definition : RNA Binding Protein EWS (656 aa, 68 kDa) is encoded by the human EWSR1 gene. This
protein plays a role in RNA binding, which may repress transcription.;
NCIt note : Ubiquitous nuclear and cytoplasmic RNA Binding Protein EWS belongs to the TET family
of RNP proteins, contains an RNA recognition motif and a RANBP2-type zinc finger,
and may function as a repressor. EWS contains a transcription activation domain, but
the RNA-binding domain can repress trans-activation by the activation domain. The
RNA-binding activity is localized to a C-terminal RGG box. EWS binds RNA, calmodulin,
and the RNA polymerase II 33 kD polypeptide (RPB3), but not RPB5 or RPB7. EWS interacts
with FAK2 and relocates from cytoplasm to ribosomes upon FAK2 activation. (SWISS-PROT);
