Does Pfam agree with the content of the Wikipedia entry ?
Pfam has chosen to link families to Wikipedia articles. In some case we have created or edited these articles but in many other cases we have not made any direct contribution to the content of the article. The Wikipedia community does monitor edits to try to ensure that (a) the quality of article annotation increases, and (b) vandalism is very quickly dealt with. However, we would like to emphasise that Pfam does not curate the Wikipedia entries and we cannot guarantee the accuracy of the information on the Wikipedia page.

Before you edit for the first time
Wikipedia is a free, online encyclopedia. Although anyone can edit or contribute to an article, Wikipedia has some strong editing guidelines and policies, which promote the Wikipedia standard of style and etiquette. Your edits and contributions are more likely to be accepted (and remain) if they are in accordance with this policy.

How your contribution will be recorded
Anyone can edit a Wikipedia entry. You can do this either as a new user or you can register with Wikipedia and log on. When you click on the "Edit Wikipedia article" button, your browser will direct you to the edit page for this entry in Wikipedia. If you are a registered user and currently logged in, your changes will be recorded under your Wikipedia user name. However, if you are not a registered user or are not logged on, your changes will be logged under your computer's IP address. This has two main implications. Firstly, as a registered Wikipedia user your edits are more likely seen as valuable contribution (although all edits are open to community scrutiny regardless). Secondly, if you edit under an IP address you may be sharing this IP address with other users. If your IP address has previously been blocked (due to being flagged as a source of 'vandalism') your edits will also be blocked. You can find more information on this and creating a user account at Wikipedia.

|Block of proliferation 1|
|RNA expression pattern|
Ribosome biogenesis protein BOP1 is a protein that in humans is encoded by the BOP1 gene. It is a WD40 repeat-containing nucleolar protein involved in rRNA processing, thereby controlling the cell cycle. It is required for the maturation of the 25S and 5.8S ribosomal RNAs. It may serve as an essential factor in ribosome formation that coordinates processing of the spacer regions in pre-rRNA. The Pes1-Bop1 complex has several components: BOP1, GRWD1, PES1, ORC6L, and RPL3 and is involved in ribosome biogenesis and altered chromosome segregation. The overexpression of BOP1 increases the percentage of multipolar spindles in human cells. Deregulation of the BOP1 pathway may contribute to colorectal tumourigenesis in humans. Elevated levels of Bop1 induces Bop1/WDR12 and Bop1/Pes1 subcomplexes and the assembly and integrity of the PeBoW complex is highly sensitive to changes in Bop1 protein levels.
Nop7p-Erb1p-Ytm1p, found in yeast, is potentially the homologous complex of Pes1-Bop1-WDR12 as it is involved in the control of ribosome biogenesis and S phase entry. The integrity of the PeBoW complex is required for ribosome biogenesis and cell proliferation in mammalian cells. In Giardia, the species specific cytoskeleton protein, beta-giardin, interacts with Bop1.
BOP1 contains a conserved N-terminal domain, BOP1NT.
