  ABSTRACT  
 
The gene encoding the regulator of chromosome condensation (RCC1) was cloned by virtue of its ability to complement the temperature-sensitive phenotype of the hamster cell line tsBN2, which undergoes premature chromosome condensation or arrest in the G1 phase of the cell cycle at non-permissive temperatures. RCC1 homologues have been identified in many eukaryotes, including budding and fission yeast. Mutations in the gene affect pre-messenger RNA processing and transport, mating, initiation of mitosis and chromatin decondensation, suggesting that RCC1 is important in the control of nucleo-cytoplasmic transport and the cell cycle. Biochemically, RCC1 is a guanine-nucleotide-exchange factor for the nuclear Ras homologue Ran; it increases the dissociation of Ran-bound GDP by 10(5)-fold. It may also bind to DNAvia a protein-protein complex. Here we show that the structure of human RCC1, solved to 1.7-A resolution by X-ray crystallography, consists of a seven-bladed propeller formed from internal repeats of 51-68 residues per blade. The sequence and structure of the repeats differ from those of WD40-domain proteins, which also form seven-bladed propellers and include the beta-subunits of G proteins. The nature of the structure explains the consequences of a wide range of known mutations. The region of the protein that is involved in guanine-nucleotide exchange is located opposite the region that is thought to be involved in chromosome binding.
 
  Selected figure(s)  
 
Figure 1.
Figure 1 Overall three-dimensional structure of RCC1. Ribbon diagram of the RCC1 propeller structure as viewed along (a) or perpendicular to (b) the central shaft. The blades (a) are numbered (B1-B7) along the sequence. Semiconserved histidines that connect the blades and invariant residues believed to be important for the interaction with Ran are shown as ball-and-stick representations.
Figure 2.
Figure 2 Primary- and secondary-structure alignment. Sequence alignment, obtained using the GCG program (adjusted manually) of five RCC1 homologues (from top to bottom: human, hamster, Drosophila, Schizosaccharomyces pombe and Saccharomyces cerevisiae) and the protein product, RPGR/RP3 of the X-linked retinitis pigmentosa gene, along with the secondary structure of human RCC1. The seven blades are coloured as in Fig. 1. Residues highly conserved in seven RCC1 homologues (including Xenopus and Caenorhabditis albicans RCC1) are boxed; invariant residues are also shown in bold. The structurally conserved residues among different repeats of RCC1 and RPGR/RP3 are shaded brown. Alanine mutations that perturb the GEF activity14 are shown in blue (human); the mutation responsible for the tsBN2 (refs 1, 2) phenotype is shown in pink (hamster); and RCC1 mutations in S. cerevisiae and S. pombe^3-7,13 are shown in red. Asterisks indicate truncated sequences.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
