It is widely expressed, and exists in both the nucleus and cytoplasm of cells where it regulates two pathways. In the nucleus, NRX may act as a transcription factor in the Wnt-pathway; a stable (reduced) NRX binds to DVL, thereby blocking downstream Wnt/beta-Catenin signaling. It also binds to PP2A subunits PP2A_C and PP2A_A, generating an active PP2A complex. Human NRX is 435 amino acids (aa) in length and contains a TXR domain (aa 167-321) that shows a WCPPC catalytic site, and a substrate recognition PDI-b' region (aa 312-427). There are three potential isoform variants. Over amino acids 131-435, human NRX shares 99% aa identity with mouse NRX.
