DNA/RNA

A: Genomic structure of BOP1: the gene extends over 29kb with 16 exons (lower part). Exons 4-16 (upper part) are clustered in 2.6 kb while exons 1-3 are separated by large (2-12 kb) introns.
Description
The BOP1 gene is situated 16.6 Mb downstream from the MYC proto-oncogene (8q24.21) and 0.8 Mb upstream from the telomere (Fig1B).
Transcription
BOP1 mRNA (NM_015201) has a size of 2422 bp.
Pseudogene
No pseudogene has been reported for BOP1, but the NCBI Map viewer (Build 36.3) displays a perfect match encompassing exons 4-16, 64kb centromeric to the gene.
Proteins

Position of the WD repeats.
Description
The Ribosome biogenesis protein BOP1 consists of 746 amino acids and has a molecular weight of 83.63 kDa. It contains 7 WD repeats.
Expression
BOP1 is expressed ubiquitously and found in nearly all tissues at similar levels.
Localisation
Nucleus, nucleolus.
Function
Required for maturation of the 25S and 5.8S ribosomal RNAs. Essential for cell proliferation. Involved in chromosomal segregation.
Homology
Mus musculus Bop1; Rattus norvegicus Bop1; Equus caballus BOP1; Bos taurus BOP1
Mutations
Note
None described to date.
Implicated in
Entity name
Colorectal cancer
Note
A copy number increase of the BOP1 gene was detected in 39% of colorectal cancer samples (n=56) and was associated with an increase of its mRNA level. This copy number increase was more frequent than that observed for MYC, a proto-oncogene located 16.6 Mb upstream from BOP1 and was distinct from MYC amplification in 16% of the cases.
Transient overexpression of BOP1 in human cells increased the percentage of abnormal mitoses with multipolar spindles.
