The protein functions as a transcriptional activator that regulates RNA polymerase II transcription, including modulation of alpha-globin gene expression in erythroid cells and repression of HIV-1 transcription. UBP1 is highly constrained against loss-of-function variants (pLI ~1.0, LOEUF 0.088), suggesting that mutations would likely cause severe developmental phenotypes. However, no specific genetic disorders have been definitively associated with UBP1 mutations in current databases.

Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). One damaged copy is likely sufficient to cause disease.
