YIP1 family member 4 (YIPF4) is a novel cellular binding partner of the papillomavirus E5 proteins
E5 proteins are amongst the least understood of the Human Papillomavirus (HPV) encoded gene products. They are small, membrane-integrated proteins known to modulate a number of critical host pathways associated with pathogenesis including growth factor receptor signaling and immune evasion. Their role in the virus life cycle is less clear, indicating a role in the productive stages of the life ...
متن کاملCellular proteins associated with the E5 oncoprotein of human papillomavirus type 16.
Human papillomavirus type 16 (HPV-16) is strongly implicated in the aetiology of premalignant and malignant disease of the cervix. The mechanisms by which HPV-16 induces cell transformation have been the subject of intense investigation for several years. The viral genome encodes three oncoproteins, E5, E6 and E7, but until recently only E6 and E7 were subjected to such scrutiny. The papillomav...
متن کاملGolgi Alkalinization by the Papillomavirus E5 Oncoprotein
The E5 oncoprotein of bovine papillomavirus type I is a small, hydrophobic polypeptide localized predominantly in the Golgi complex. E5-mediated transformation is often associated with activation of the PDGF receptor (PDGF-R). However, some E5 mutants fail to induce PDGF-R phosphorylation yet retain transforming activity, suggesting an additional mechanism of action. Since E5 also interacts wit...
متن کاملEconomic Galileo E5 Receiver
The Galileo system introduces an extremely wideband civil E5 signal for high precision navigation. The structure of the receiver for the E5 signal is complicated due to the signal complexity and the large bandwidth. It is possible to process the whole E5 signal or process separately E5a and E5b parts combining obtained results afterwards (we call here such method as piece-wise processing). The ...
متن کاملDown-regulation of MHC class I is a property common to papillomavirus E5 proteins.
The E5 protein family of papillomaviruses comprises small hydrophobic proteins which are associated with the cell endomembrane compartments. The functions of the E5 proteins, particularly those of HPV, are still far from clear. We have reported that the E5 proteins of BPV-1, BPV-4, HPV-16 and HPV-6 down-regulate MHC class I, potentially helping the virus evade the host immune response. Others h...
