Entrez Gene Summary for UBAP1 Gene

  • This gene is a member of the UBA domain family, whose members include proteins having connections to ubiquitin and the ubiquitination pathway. The ubiquitin associated domain is thought to be a non-covalent ubiquitin binding domain consisting of a compact three helix bundle. This particular protein originates from a gene locus in a refined region on chromosome 9 undergoing loss of heterozygosity in nasopharyngeal carcinoma (NPC). Taking into account its cytogenetic location, this UBA domain family member is being studies as a putative target for mutation in nasopharyngeal carcinomas. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2010]

GeneCards Summary for UBAP1 Gene

UBAP1 (Ubiquitin Associated Protein 1) is a Protein Coding gene. Diseases associated with UBAP1 include nasopharyngeal carcinoma and intermediate coronary syndrome. GO annotations related to this gene include ubiquitin binding. An important paralog of this gene is UBAP1L.

UniProtKB/Swiss-Prot for UBAP1 Gene

  • 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.

    Quaternary structure:
    • 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) (PubMed:22405001), but may have a preference for the ESCRT-I complex containing VPS37A (PubMed:21757351). Interacts with PTPN23. Interacts (via UBA domains) with ubiquitinated proteins.
