"Темный протеом" - белки, структуры которых совершенно неизвестны - является ключевым в нашем понимании биологических систем. Новое исследование показывает, что в настоящее время примерно половина протеома у эукариот и вирусов темное, необходимы более чувствительные инструменты для изучения полной белковой вселенной.

The "dark proteome" — protein regions whose structures are completely unknown — is a key remaining frontier in our understanding of biological systems. A new study now shows that roughly half of the proteome in eukaryotes and viruses is dark, highlighting the need for more sensitive tools to explore the full expanse of the protein universe [Weaver2016].

Fig. 5 from [Perdigao2015]. Cellular locations over- and underrepresented in dark proteins. Pooling annotations for all eukaryotic proteins, we determined which subcellular compartments were enriched in dark proteins; these proteins were most strongly overrepresented in the extracellular space, followed by the endoplasmic reticulum and then the plasma membrane. Dark proteins were underrepresented among cytoplasmic proteins.
