Cell corpse engulfment mediated by C. elegans phosphatidylserine receptor through CED-5 and CED-12.
During apoptosis, phosphatidylserine, which is normally restricted to the inner leaflet of the plasma membrane, is exposed on the surface of apoptotic cells and has been suggested to act as an "eat-me" signal to trigger phagocytosis. It is unclear how phagocytes recognize phosphatidylserine. Recently, a putative phosphatidylserine receptor (PSR) was identified and proposed to mediate recognitio...
متن کاملCandidate Adaptor Protein CED-6 Promotes the Engulfment of Apoptotic Cells in C. elegans
The rapid engulfment (phagocytosis) of cells undergoing programmed cell death (apoptosis) is a fundamental biological process that is not well understood. Here we report the cloning and functional characterization of ced-6, a gene specifically required for the engulfment of apoptotic cells in the nematode C. elegans. The CED-6 protein contains a phosphotyrosine binding domain at its N terminus ...
متن کاملCED-1 Is a Transmembrane Receptor that Mediates Cell Corpse Engulfment in C. elegans
We cloned the C. elegans gene ced-1, which is required for the engulfment of cells undergoing programmed cell death. ced-1 encodes a transmembrane protein similar to human SREC (Scavenger Receptor from Endothelial Cells). We showed that ced-1 is expressed in and functions in engulfing cells. The CED-1 protein localizes to cell membranes and clusters around neighboring cell corpses. CED-1 failed...
متن کاملHuman CED-6 encodes a functional homologue of the Caenorhabditis elegans engulfment protein CED-6
The rapid engulfment of apoptotic cells is a specialized innate immune response used by organisms to remove apoptotic cells. In mammals, several receptors that recognize apoptotic cells have been identified; molecules that transduce signals from these receptors to downstream cytoskeleton molecules have not been found, however [1] [2] [3]. Our previous analysis of the engulfment gene ced-6 in Ca...
متن کاملThe C. elegans Cell Corpse Engulfment Gene ced-7 Encodes a Protein Similar to ABC Transporters
The C. elegans gene ced-7 functions in the engulfment of cell corpses during programmed cell death. We report that the CED-7 protein has sequence similarity to ABC transporters, is broadly expressed during embryogenesis, and is localized to the plasma membrane. Mosaic analysis revealed that ced-7 functions in both dying cells and engulfing cells during the engulfment process. We propose that CE...
