The c11orf98 protein contains a region of unknown function (DUF5564) that spans from amino acids 1-98. There are also 2 disordered regions within the protein that span from amino acids 1-21 and 32-123. C11orf98 contains 4 bipartite nuclear localization signals (NLS_BP) which indicates the protein will be 'tagged' for import into the cell nucleus by nuclear transport. The NLS_BP sequence usually consists of positively charged arginines, which would also explain the arginine rich region (ARG_RICH).
