Summaries for PQBP1 Gene

Entrez Gene Summary for PQBP1 Gene

  • This gene encodes a nuclear polyglutamine-binding protein that is involved with transcription activation. The encoded protein contains a WW domain. Mutations in this gene have been found in patients with Renpenning syndrome 1 and other syndromes with X-linked mental retardation. Multiple alternatively spliced transcript variants that encode different protein isoforms have been described for this gene.[provided by RefSeq, Nov 2009]

GeneCards Summary for PQBP1 Gene

PQBP1 (Polyglutamine Binding Protein 1) is a Protein Coding gene. Diseases associated with PQBP1 include renpenning syndrome and x-linked intellectual disability, golabi-ito-hall type. Among its related pathways are Spliceosome. GO annotations related to this gene include transcription coactivator activity.

UniProtKB/Swiss-Prot for PQBP1 Gene

  • Probably functions as scaffold protein that is part of numerous complexes and thereby plays a role in pre-mRNA splicing, transcription regulation and neuron development. Required for normal alternative splicing of target pre-mRNA species (PubMed:23512658). May suppress the ability of POU3F2 to transactivate the DRD1 gene in a POU3F2 dependent manner. Can activate transcription directly or via association with the transcription machinery. May be involved in ATXN1 mutant-induced cell death. The interaction with ATXN1 mutant reduces levels of phosphorylated RNA polymerase II large subunit.

    • Interacts with POU3F2/Brn-2, ATXN1, TXNL4A, HTT and AR. Interaction with ATXN1 correlates positively with the length of the polyglutamine tract. Interacts with RNA polymerase II large subunit in a phosphorylation-dependent manner. Forms a ternary complex with ATXN1 mutant and phosphorylated RNA polymerase II. Interacts (via C-terminus) with TXNL4A and CD2BP2. Interacts (via WW domain) with ATN1, WBP11 and SF3B1, and may interact with additional splice factors.

PQBP1_HUMAN
  • Renpenning syndrome 1 (RENS1) [MIM:309500]: A X-linked mental retardation syndrome characterized by mental retardation, microcephaly, short stature, and small testes. The craniofacies tends to be narrow and tall with upslanting palpebral fissures, abnormal nasal configuration, cupped ears, and short philtrum. The nose may appear long or bulbous, with overhanging columella. Less consistent manifestations include ocular colobomas, cardiac malformations, cleft palate, and anal anomalies. {ECO:0000269 PubMed:14634649, ECO:0000269 PubMed:16740914}. Note=The disease is caused by mutations affecting the gene represented in this entry.
