The single subunit transmembrane E3 ligase
gene related to anergy in lymphocytes (GRAIL) captures and then ubiquitinates transmembrane proteins across the cell membrane.

TNFAIP3 is a ubiquitin-editing enzyme that participates in ubiquitin ligase
and deubiquitinase activities.
To test whether Hbo1 alone has ubiquitin E3 ligase
activity, an array of E2 ubiquitin conjugating enzymes for self-ubiquitination of commercial Hbo1 protein were screened by mixing commercial recombinant Hbo1 protein with E1, E2, ATP, and biotinylated ubiquitin and probing with Cy5-conjugated streptavidin (Fig.
The glutamate-cysteine ligase
modifier subunit (GCLM) and the glutamate-cysteine ligase
catalytic subunit (GCLC) form the glutathione cysteine ligase
(GCL) that catalyzes the conversion of glutamate and cysteine into y-glutamyl cysteine, a glutathione precursor .
Located at the N-terminal region of pCAF, lies a domain containing ubiquitin E3 ligase

These results suggested that siRNA-mediated knockdown of PIASy inhibited the sumoylation of IKK[gamma] and the activation of NF-[kappa]B inflammatory signaling; in other words, the SUMO E3 ligase
PIASy plays an important role in the activation of NF-[kappa]B signaling induced by high glucose.
