Abstract
The steroid receptor RNA activator gene (SRA1) produces both a functional RNA (SRA) and a protein (SRAP), whose exact physiological roles remain unknown. To identify cellular processes regulated by SRAP we compared the transcriptome of Hela and MDA-MB-231 cancer cells upon depletion of the SRA/SRAP transcripts or overexpression of the SRAP protein. RNA-seq and Ontology analyses pinpointed cellular movement as potentially regulated by SRAP. Using live cell imaging, we found that SRA/SRAP depletion and SRAP overexpression lead respectively to a decrease and increase in cancer cell motility. Our results highlight for the first time a link existing between SRA1 gene expression and cell motility.
