Transposable elements have contributed to thousands of human proteins.

ABSTRACT: This is a report of many distant but significant protein sequence relationships between human proteins and transposable elements (TEs). The libraries of human repeated sequences contain the DNA sequences of many TEs. These were translated in all reading frames, ignoring stop codons, and were used as amino acid sequence probes to search with BLASTP for similar sequences in a library of 25,193 human proteins. The probes show regions of significant amino acid sequence similarity to 1,950 different human genes, with an expectation of <10(-3). In comparison with previous REPEATMASKER (Institute for Systems Biology, Seattle) studies, these probes detect many more TE sequences in more human coding sequences with greater length than previous work using DNA sequences. If the criterion is opened, ve
