Target

Function
Transcription factor that binds to the octamer motif (5'-ATTTGCAT-3') and activates the promoters of the genes for some small nuclear RNAs (snRNA) and of genes such as those for histone H2B and immunoglobulins. Modulates transcription transactivation by NR3C1, AR and PGR (By similarity). In case of human herpes simplex virus (HSV) infection, POU2F1 forms a multiprotein-DNA complex with the viral transactivator protein VP16 and HCFC1 thereby enabling the transcription of the viral immediate early genes. -
Tissue specificity
Ubiquitous. Isoform 2 is lymphocyte-specific. -
Sequence similarities
Belongs to the POU transcription factor family. Class-2 subfamily.
Contains 1 homeobox DNA-binding domain.
Contains 1 POU-specific domain. -
Post-translational
modificationsPhosphorylated by PRKDC. -
