Tripartite motif-containing protein 5 also known as RING finger protein 88 is a protein that in humans is encoded by the TRIM5 gene .[ 5] The alpha isoform of this protein, TRIM5α , is a retrovirus restriction factor, which mediates a species-specific early block to retrovirus infection.
TRIM5α is composed of 493 amino acids which 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,[ 6] [ 7] tetherin and TRIM22 .
