Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0007609
UniProt IDQ13049
Primary gene name(s)TRIM32
Synonym gene name(s)HT2A
Protein nameE3 ubiquitin-protein ligase TRIM32
Protein functionHas an E3 ubiquitin ligase activity. Ubiquitinates DTNBP1, dysbindin and promotes its degradation. May ubiquitinate BBS2. May play a significant role in mediating the biological activity of the HIV-1 Tat protein in vivo. Binds specifically to the activation domain of HIV-1 Tat and can also interact with the HIV-2 and EIAV Tat proteins in vivo. {ECO:0000269|PubMed:19349376, ECO:0000269|PubMed:22500027}.
Subcellular locationCytoplasm. Note=Localized in cytoplasmic bodies, often located around the nucleus.
