Names and origin

Protein namesRecommended name:
Ubiquitin-conjugating enzyme E2 J2

EC=6.3.2.19
Gene names
Name:ube2j2
ORF Names:DDB_G0286511
OrganismDictyostelium discoideum (Slime mold) [Reference proteome]
Taxonomic identifier44689 [NCBI]
Taxonomic lineageEukaryotaAmoebozoaMycetozoaDictyosteliidaDictyostelium

Protein attributes

Sequence length241 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Catalyzes the covalent attachment of ubiquitin to other proteins. Seems to function in the selective degradation of misfolded membrane proteins from the endoplasmic reticulum By similarity.

Catalytic activity

ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine.

Pathway

Protein modification; protein ubiquitination.

Subcellular location

Endoplasmic reticulum membrane; Single-pass type IV membrane protein By similarity.

Sequence similarities

Belongs to the ubiquitin-conjugating enzyme family.
