FunFam 6042: Ubiquitin-conjugating enzyme E2 Q2

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 6 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.

GO Term Annotations Evidence
Protein K48-linked ubiquitination GO:0070936
A protein ubiquitination process in which a polymer of ubiquitin, formed by linkages between lysine residues at position 48 of the ubiquitin monomers, is added to a protein. K48-linked ubiquitination targets the substrate protein for degradation.

Suckling behavior GO:0001967
Specific behavior of a newborn or infant mammal that results in the derivation of nourishment from the breast.
1 Q7TSS2 (/IMP)
Embryo implantation GO:0007566
Attachment of the blastocyst to the uterine lining.

1 Q7TSS2 (/IMP)
Fertilization GO:0009566
The union of gametes of opposite sexes during the process of sexual reproduction to form a zygote. It involves the fusion of the gametic nuclei (karyogamy) and cytoplasm (plasmogamy).
1 Q7TSS2 (/IMP)
Protein ubiquitination GO:0016567
The process in which one or more ubiquitin groups are added to a protein.
