WebThe endoplasmic reticulum. The endoplasmic reticulum ( ER) plays a key role in the modification of proteins and the synthesis of lipids. It consists of a network of membranous tubules and flattened sacs. The discs and tubules of the ER are hollow, and the space inside is called the lumen. WebHIV uses an efficient mechanism to dislocate a single-membrane-spanning host protein, CD4, from the ER and submits it to ERAD. The Vpu protein of HIV-1 is a protein on the ER membrane and targets newly made CD4 in the endoplasmic reticulum for degradation by cytosolic proteasomes. Vpu only utilizes part of the ERAD process to degrade CD4.
