Cotransin

Cotransin is a Sec61 translocation inhibitor that acts in a signal-sequence-discriminatory manner to prevent the stable insertion of select nascent chains into the Sec61 translocation channel. Cotransin selectively inhibits the expression of VCAM-1 and p-selectin proteins by inhibiting their co-translational translocation across endoplasmic reticulum (ER) membranes (IC50=0.5-5 µM). Cotransin has potential for studying inflammation and immunity.
