Description

Tripartite motif-containing protein 5 (TRIM5) is a RING domain-E3 ubiquitin ligase that restricts infection by human immunodeficiency virus (HIV)-1 and other retroviruses immediately following virus invasion of the target cell cytoplasm [PMID: 21512573]. It is a regulator of autophagy [PMID: 25127057].

Interestingly, while each primate species has a single TRIM5 gene, mice have at least seven TRIM5 homologues that cluster into two groups, Trim12a, -b, and -c and Trim30a, -b, -c, and -d. The three Trim12 proteins activated innate immune signaling, while the Trim30 proteins did not [PMID: 26468522].
