| Name | IMP4, U3 small nucleolar ribonucleoprotein |
| Description | The protein encoded by this gene, along with IMP3 and MPP10, is part of the 60-80S U3 small nucleolar ribonucleoprotein (U3 snoRNP) complex. This complex is necessary for the early cleavage steps of pre-18S ribosomal RNA processing. Several transcript variants encoding different isoforms have been found for this gene.

| Summary |
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\n IMP4 is one of the protein components of the small subunit (SSU) processome—a large ribonucleoprotein complex that orchestrates the processing, assembly, and maturation of the eukaryotic small ribosomal subunit. Available evidence indicates that IMP4 contributes to the early steps of pre‐rRNA processing by forming part of the dynamic network of protein–protein and protein–RNA interactions that stabilize and organize the SSU processome. In this role, IMP4 is thought to help recruit or coordinate the function of the U3 small nucleolar RNA (snoRNA) and other associated factors, thereby acting as a scaffold or mediator to ensure the proper assembly of the early ribosome biogenesis machinery. Although comprehensive interaction maps remain incomplete—with many interactions still to be identified—the inclusion of IMP4 among the processome components emphasizes its importance in the formation and function of subcomplexes critical for pre‐rRNA cleavage and ribosome assembly."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n "}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Young H Lim, J Michael Charette, Susan J Baserga "}, {"type": "b", "children": [{"type": "t", "text": "Assembling a protein-protein interaction map of the SSU processome from existing datasets."}]}, {"type": "t", "text": " "}, {"type": "i", "children": [{"type": "t", "text": "PLoS One (2011)"}]}, {"type": "t", "text": " DOI: "}, {"type": "a", "children": [{"type": "t", "text": "10.1371/journal.pone.0017701"}], "href": "https://doi.org/10.1371/journal.pone.0017701"}, {"type": "t", "text": " PMID: "}, {"type": "a", "children": [{"type": "t", "text": "21423703"}], "href": "https://pubmed.ncbi.nlm.nih.gov/21423703"}]}, {"type": "r", "ref": 2, "children": [{"type": "t", "text": "Kathleen R Phipps, J Michael Charette, Susan J Baserga "}, {"type": "b", "children": [{"type": "t", "text": "The small subunit processome in ribosome biogenesis—progress and prospects."}]}, {"type": "t", "text": " "}, {"type": "i", "children": [{"type": "t", "text": "Wiley Interdiscip Rev RNA (2011)"}]}, {"type": "t", "text": " DOI: "}, {"type": "a", "children": [{"type": "t", "text": "10.1002/wrna.57"}], "href": "https://doi.org/10.1002/wrna.57"}, {"type": "t", "text": " PMID: "}, {"type": "a", "children": [{"type": "t", "text": "21318072"}], "href": "https://pubmed.ncbi.nlm.nih.gov/21318072"}]}]}]}
