endosome (plural endosomes)
(biology) An endocytic vacuole through which molecules internalized during endocytosis pass en route to lysosomes
Downregulation occurs when endocytosed receptor is embedded in an endosome that is trafficked to merge with an organelle called a lysosome. Source: Internet
The late endosome itself can eventually grow into a mature lysosome, as evidenced by the transport of endosomal membrane components from the lysosomes back to the endosomes. Source: Internet
Inside the endosome, the toxin is split by a trypsin-like protease into its individual A and B fragments. Source: Internet
The low pH within the endosome then triggers BTV's membrane penetration protein VP5 to undergo a conformational change that disrupts the endosomal membrane. Source: Internet
