MyHits: improvements to an interactive resource for analyzing protein sequences.

abstract：:HBV genotypes differ in pathogenicity. In addition, genotype-specific differences in the regulation of transcription and virus replication exist in HBV, but the underlying mechanisms are unknown. Here, we show the presence of a G-quadruplex motif in the promoter of the preS2/S gene; this G-quadruplex is highly conserv...
