Two seemingly intact env genes not detected in the recent survey of intact human envelope genes [41] are equally interesting in terms of possible ... [2]. Finally, screening the human genome in silico does not guarantee detection of polymorphic HERV loci in which the empty pre-integra- tion site is still segrega...

... inter- acts with the carboxy-terminal domain of REST, could increase the methylations in H3K9, predominantly di-meth- ylation in nucleosomes within 2-kb regions of RE1s [41]. Our analyses demonstrate ... activity profiles associated with their binding of RE1s and the recruiting of selective histone modi- fying enzymes. In fact, one truncated isoform, REST4, has been found...
