Anti-CSDE1/NRU Antibody Picoband®

Cold shock domain-containing protein E1 is a protein that in humans is encoded by the CSDE1 gene. Originally described as the product of an active transcription unit located upstream of the N-RAS gene, CSDE1 (cold shock domain-containing protein E1) is a highly conserved RNA-binding protein containing five cold-shock domains. CSDE1 is mostly localized in the cytoplasm where it interacts with distinct protein complexes involved in the post-transcriptional regulation of numerous mRNAs in a dynamic and complex manner. CSDE1 plays a role in maintaining the undifferentiated state of human embryonic stem cells (hESCs), and its loss results in accelerated neural differentiation and neurogenesis, partially via post-transcriptional regulation of fatty acid binding protein 7 (FABP7) and vimentin (VIM) mRNAs. In human melanoma, increased CSDE1 protein expression has been shown to modulate the levels of pro-oncogenic factors such as vimentin or RAC1 and tumor suppressors such as PTEN, thus promoting tumor invasion and metastasis.
