Terminal lysosomes
Web2 May 2024 · While endo-lysosomes contain active acidic hydrolases, scientists also observed so-called terminal lysosomes containing inactive acidic hydrolases. However, they are not post-lysosomes or inert residual bodies, but they can provide digestive enzymes for reusage in the lysosome reformation process (Bright et al., 1997). The transport of ... Web15 Oct 2024 · LITAF, also known as SIMPLE (Small integral membrane protein of the lysosome/late endosome), encodes a widely-expressed 17 kDa monotopic integral membrane protein composed of an N-terminal proline-rich region and an evolutionary conserved zinc-binding C-terminal ‘LITAF domain’ that anchors the protein to endosomal …

Web11 Jul 2011 · Overexpression of the C-terminal half of RILP resulted in lysosome dispersal and inhibition of lysosomal substrate degradation, similar to that observed in cells expressing the inactive GDP-bound RAB7 mutant. Overexpression of RILP was able to prevent or reverse the effects of the inactive RAB7 mutant, leading Cantalupo et al. (2001) … WebHere, it was shown that, in cells transfected with plasmid that encodes glycoprotein with c-CD63 motif at the C-terminus, the chimeric protein was predominantly observed in lysosomes and at the cell membrane where the unmodified glycoprotein is localized in the endoplasmic reticulum and at the cell surface.
