Summary

UTP4 (UTP4 small subunit processome component, HGNC:1983) is a protein-coding gene on chromosome 16q22.1, encoding U3 small nucleolar RNA-associated protein 4 homolog (Q969X6). Ribosome biogenesis factor. It is a common-essential gene (DepMap: required in 99.8% of cancer cell lines).

This gene encodes a WD40-repeat-containing protein that is localized to the nucleolus. Mutation of this gene causes North American Indian childhood cirrhosis, a severe intrahepatic cholestasis that results in transient neonatal jaundice, and progresses to periportal fibrosis and cirrhosis in childhood and adolescence. Alternative splicing results in multiple transcript variants.

Literature-anchored findings (GeneRIF, showing 4)

  • A missense mutation (R565W) in cirhin (FLJ14728) in North American Indian childhood cirrhosis (PMID:12417987)
  • Cirhin is a nucleolar protein and the R565W mutation, for which all North American Indian childhood cirrhosis patients are homozygous, has no effect on subcellular localization. (PMID:16225863)
  • Cirhin is a transcriptional regulatory factor of this NF-kappaB sequence and could be a participant in the regulation of other genes with NF-kappaB responsive elements. (PMID:19732766)
  • Results show that CIRH1A was highly expressed in carcinoma samples and colorectal cancer cells and suggest that CIRH1A plays a critical role in the proliferation, cell cycle distribution, and apoptosis of human malignant colorectal cells. (PMID:28350096)

Function. Ribosome biogenesis factor. Involved in nucleolar processing of pre-18S ribosomal RNA. Part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit. During the assembly of the SSU processome in the nucleolus, many ribosome biogenesis factors, an RNA chaperone and ribosomal proteins associate with the nascent pre-rRNA and work in concert to generate RNA folding, modifications, rearrangements and cleavage as well as targeted d Involved in SSU pre-rRNA processing at sites A’, A0, 1 and 2b. Required for optimal pre-ribosomal RNA transcription by RNA polymerase. May be a transcriptional regulator. (Microbial infection) Acts as a positive regulator of HIVEP1 which specifically binds to the DNA sequence 5’-GGGACTTTCC-3’ found in enhancer elements of numerous viral promoters such as those of HIV-1, SV40, or CMV.

Subunit / interactions. Interacts with HIVEP1 Interacts with NOL11. Part of the small subunit (SSU) processome, composed of more than 70 proteins and the RNA chaperone small nucleolar RNA (snoRNA) U3. May be a component of the proposed t-UTP subcomplex of the ribosomal small subunit (SSU) processome containing at least UTP4, WDR43, HEATR1, UTP15, WDR75.

Subcellular location. Nucleus. Nucleolus. Chromosome.

Post-translational modifications. May be phosphorylated during mitosis; may control the association of this protein with WRD43 and UTP15.

Miscellaneous. May be due to intron retention.
