motifs/domains
  • 200 amino acid C-terminal domain containing two long hydrophobic sequences
  • two transmembrane helices and the N- and C-terminal regions which are supposed in the cytosolic side of ER
  • a C-terminal reticulon homology domain containing two hydrophobic segments and a 66-amino acid hydrophilic loop
  • HOMOLOGY

  • anchored to membranes of the endoplasmic reticulum through its carboxy-terminal regions
  • Mutant proteins lacking the first (39 residues) or second (36 residues) hydrophobic segment showed ER localization, but mutant lacking both hydrophobic segments was cytosolic
  • MANF co-localized with RTN1 in the ER
  • basic FUNCTION
  • maybe involved in neuroendocrine secretion and membrane trafficking not inhibiting axonal regeneration
  • RTN1 and RYR2 might act as functional partners in the regulation of cytosolic Ca(2+) dynamics the in neurons

  • RYR2 is a direct binding partner of RTN1, and RTN1 and RYR2 might act as functional partners in the regulation of cytosolic Ca(2+) dynamics the in neurons
  • induces PDI redistribution in ER vesicles, and concomitantly modulates its activity by decreasing the levels of its S-nitrosylated form
