Facts about Tripartite motif-containing protein 5.
In addition to acting as a capsid-specific restriction factor, also functions as a pattern recognition receptor which triggers innate immune signaling in response to the retroviral capsid lattice. Binding to the viral capsid triggers its E3 ubiquitin ligase activity, and in concert with the heterodimeric ubiquitin conjugating enzyme complex UBE2V1-UBE2N (also known as UBC13-UEV1A complex) generates'Lys-63'-linked polyubiquitin chains, which then are catalysts in the autophosphorylation of the MAP3K7/TAK1 complicated (contains TAK1, TAB2, and TAB3).

Cytoplasm. Nucleus. Predominantly localizes in cytoplasmic bodies (PubMed:12878161, PubMed:20357094). Localization may be influenced by the coexpression of other TRIM proteins, hence partial nuclear localization is observed in the presence of TRIM22 or TRIM27 (By similarity). In cytoplasmic bodies, colocalizes with proteasomal subunits and SQSTM1 (By similarity).
