PAX5 (human)

PAX5 May play an important role in B-cell differentiation as well as neural development and spermatogenesis. Involved in the regulation of the CD19 gene, a B-lymphoid-specific target gene. Interacts with DAXX. Binds DNA as a monomer. Binds TLE4. Note: This description may include information from UniProtKB.
Cellular Component: nucleus
Molecular Function: DNA binding; transcription factor activity
Biological Process: negative regulation of histone H3-K9 methylation; transcription from RNA polymerase II promoter; nervous system development; organ morphogenesis; multicellular organismal development; positive regulation of transcription from RNA polymerase II promoter; spermatogenesis; negative regulation of transcription from RNA polymerase II promoter; humoral immune response
Reference #:  Q02548 (UniProtKB)
Alt. Names/Synonyms: B cell specific activator protein; B-cell lineage specific activator; B-cell-specific transcription factor; BSAP; paired box 5; paired box homeotic gene 5; Paired box protein Pax-5; PAX5; transcription factor PAX 5
