High impact information on canx

  • Calnexin is a membrane protein of the endoplasmic reticulum that associates transiently with newly synthesized N-linked glycoproteins in vivo [1].
  • Using defined components, the binding of ribonuclease B (RNase B) Man7-Man9 glycoforms to the luminal domain of calnexin was observed in vitro only if RNase B was monoglucosylated [1].
  • The findings suggest that discrete populations of nonnative conformations are selectively reglucosylated to participate in the calnexin/calreticulin chaperone pathway [2].
  • This indicated that the lectin-like interaction, and not a protein-protein interaction, played the central role in stabilizing RNase-calnexin/calreticulin complexes [3].
  • Immunoprecipitation followed by immunoblot analysis showed that IR precursor was associated with calnexin (CNX) to a greater extent in GA-treated cells, compared with nontreated cells [4].

Biological context of canx


Associations of canx with chemical compounds

  • Thus, inhibition of the Hsp90 family by GA or HA interrupts homodimerization of monomeric IR precursor in the ER and increases retention of monomeric IR precursor with CNX; this event retards cell surface expression of IR and attenuates insulin-induced activation of IRS-1 [4].
  • In the presence of NB-DNJ, the interaction of E1 and E2 with calnexin is prevented, leading to misfolding of the envelope glycoproteins and inefficient formation of E1-E2 heterodimers [5].
