Dinoflagellate/viral nucleoproteins (DVNPs) are a family of positively-charged,
The proteins are known to pack DNA more tightly than histones do. When expressed in eukaryotes that possess histones, they displace
dinoflagellate histone-like proteins (HLPs) for packaging.[3]
The version of DVNPs in dinoflagellates have a variable N-terminal tail with a
nuclear localization signal. It also has many phosphorylation sites, a feature not seen in viral counterparts. The fixed C-terminal domain may have a helix-turn-helix fold.[4]
