Functional Description
 E3 ubiquitin-protein ligase. Mediates TSG101 monoubiquitination at multiple sites. Plays a role in the regulation of endosome-to-lysosome trafficking. Impairs MC1R- and MC4R-signaling by competing with GNAS-binding to MCRs and inhibiting agonist-induced cAMP production. Does not inhibit ADRB2-signaling. Does not promote MC1R ubiquitination (By similarity). 
Sequence Annotation
 ZN_FING 277 316 RING-type.
 MOTIF 384 387 Required for TSG101-binding.
 MOD_RES 501 501 Phosphoserine (By similarity).
 LIPID 2 2 N-myristoyl glycine (By similarity).
