neXtProt entry for CLSTN2 Gene

Post-translational modifications for CLSTN2 Gene

  • Proteolytically processed under normal cellular conditions. A primary zeta-cleavage generates a large extracellular (soluble) N-terminal domain (sAlc) and a short C-terminal transmembrane fragment (CTF1). A secondary cleavage catalyzed by gamma-secretase within the transmembrane domain releases the beta-Alc-gamma chain in the extracellular milieu and produces an intracellular fragment (AlcICD). This processing is strongly suppressed in the tripartite complex formed with APBA2 and APP, which seems to prevent the association with PSEN1 (By similarity).
  • Glycosylation at Asn56, Asn98, posLast=342342, Asn374, posLast=716716, and posLast=729729
