What regulates the antiviral activity of IFITM3? | Recent genomic research has revealed that there are 5 IFITM members in humans IFITM1, 2, 3, 5 and 10 and 7 members in mice IFITM1, 2, 3, 5, 6, 7, and 10 . These proteins play roles in diverse biological processes, such as germ cell maturation during gastrulation IFITM1-3 , cell-to-cell adhesion IFITM1 , antiviral act... | Recently, one of the interferon-induced transmembrane IFITM family proteins, IFITM3, has become an important target for the activity against influenza A H1N1 virus infection. In this protein, a post-translational modification by fatty acids covalently attached to cysteine, termed S-palmitoylation, plays a crucial role ... | 650 |

The S-palmitoylation leads to the clustering and the correct positioning of IFITM3 molecules in the membrane iii . The Spalmitoylation and the following clustering are crucial for the resistanc... | 650 |

The band corresponding to FLAG peptide is not shown because of the smaller molecular-mass of FLAG peptide relative to FKBP11-FLAG. C The control experiment of Figure 4 ... | 650 |
What is another name for IFITM5? | The other IFITM family members also possess these cysteines Figure 1-A , and thus the role of the Spalmitoylation on the cysteines should be significant for the functions of IFITM proteins. Here, we focused on IFITM5, which is also known as bonerestricted IFITM-like BRIL protein . Among the IFITM family proteins, IFITM... | IFITM5 is another IFITM family protein and interacts with the FK506-binding protein 11 FKBP11 to form a higher-order complex in osteoblast cells, which induces the expression of immunologically relevant genes. In this study, we investigated the role played by S-palmitoylation of IFITM5 in its interaction with FKBP11 in... | 650 |

Amino-acid sequence similarity: The amino acid sequence of IFITM5 is relatively dissimilar to IFITM1-3 proteins ~ 65% similarity , while IFITM1-3 proteins share ~ 85% similarit... | 650 |

In addition, the bands corresponding to the high and the low molecular-mass forms shown in western blot analysis were tentatively assigned to the S-palmitoylated and the depalmitoylated forms, respectively. As described... | 650 |
