DNA/RNA

Atlas Image
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.
