UniProtKB - O94464 (NVJ2_SCHPO)
Protein
Nucleus-vacuole junction protein 2
Gene
nvj2
Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Functioni
During endoplasmic reticulum (ER) stress or when cellular ceramide levels increase, induces contacts between the ER and medial-Golgi complex to facilitate non-vesicular transport of ceramides from the ER to the Golgi complex where they are converted to complex sphingolipids, preventing toxic ceramide accumulation.
