Abstract: The intrinsically disordered sequences—or “intrinsically disorded sequences” or IDSeq—proteins should be flexible to ensure a controlled interaction between proteins. In the development of the diseases, IDSeq are modified and polymerized. The invention describes the method of preparation of the drugs against cancers, the degenerative diseases and the infectious illness, by the induction of an immune reaction against IDSeq modified in a covalent way (IDSeqC) and polymerized (pIDSeqC), and leading to a new network of protein signaling, named here “misfoldome”, causing the diseases. The invention describes the preparation of vaccines by the use of polymers of IDSeqC. Peptides of the pIDSeqC are prepared in vitro, and introduced into a living organism to induce an immunological response, which eliminates the “misfoldome” and cures the diseases. The method is employed for the preparation of active or passive vaccines.

The present invention further provides methods for adapting plants and animals to survive outside their native environments. In particular, undifferentiated cells from plants or animals are replicated under weightless conditions in which cell replication or proliferation is accelerated and sustained. Under such conditions, the undifferentiated cells can be “forced” to express sets of genes useful for survival in particular environmental conditions. In this manner, cells surviving prolonged exposure to specific environmental conditions can be selected for and cultivated to produce an organism adapted to that particular environment in an accelerated manner.

Abstract: In accordance with the present invention, a family of membrane fusion protein and polynucleotides encoding the proteins have been identified.

The genes encoding these proteins have been cloned and sequenced. Analysis of the amino acid sequences of these proteins show that both lack the typical fusion peptide motif found in other membrane fusion proteins. Expression of these proteins in cells results in cell-cell fusion.
