Ubiquitin-associated protein 1

Gene

Ubap1

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Experimental evidence at transcript leveli

Functioni

Component of the ESCRT-I complex, a regulator of vesicular trafficking process. Binds to ubiquitinated cargo proteins and is required for the sorting of endocytic ubiquitinated cargos into multivesicular bodies (MVBs). Plays a role in the proteasomal degradation of ubiquitinated cell-surface proteins, such as EGFR and BST2 (By similarity).By similarity

Interactioni

Subunit structurei

Component of an ESCRT-I complex (endosomal sorting complex required for transport I) which consists of TSG101, VPS28, VPS37A and UBAP1 in a 1:1:1:1 stoechiometry. Can be a component of ESCRT-I complexes containing VPS37B, VPS37C and VPS37D (in vitro), but may have a preference for the ESCRT-I complex containing VPS37A. Interacts with PTPN23. Interacts (via UBA domains) with ubiquitinated proteins (By similarity).By similarity

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
