FunFam 415: Ubiquitin regulatory X

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 2 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

Endoplasmic reticulum GO:0005783
The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).

Dsc E3 ubiquitin ligase complex GO:0044695
An E3 ubiquitin ligase complex localized to the ER and Golgi membrane. In fission yeast comprises Dsc1, 2, 3 and 4. Involved in the processes of fission yeast sre1 (human SREBP) transcriptional activator proteolytic cleavage, the multivesicular body (MVB) pathway, and a post-endoplasmic reticulum pathway for protein catabolism.
