Tripartite motif-containing protein 5 also known as RING finger protein 88 is a protein that in humans is encoded by the TRIM5 gene. The alpha isoform of this protein, TRIM5α, is a retrovirus restriction factor, which mediates species-specific, early block to retrovirus infection.
TRIM5α is composed of 493 amino acids that is found in the cells of most primates. TRIM5α is an intrinsic immune factor important in the innate immune defense against retroviruses, along with the APOBEC family of proteins, tetherin and TRIM22.
