== Function ==
 +
[https://www.uniprot.org/uniprot/PO2F1_HUMAN PO2F1_HUMAN] 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.<ref>PMID:1684878</ref>

== Publication Abstract from PubMed ==
 +
The POU-specific (POUs) domain, in association with a POU-type homeodomain, forms the bipartite DNA-binding POU domain. The solution structure of the Oct-1 POUs domain has been determined by multidimensional nuclear magnetic resonance spectroscopy and consists of four alpha helices surrounding a conserved hydrophobic core. The POUs domain is structurally similar to the DNA-binding domains of the bacteriophage lambda and 434 repressors and 434 Cro. These domains exhibit superimposable helix-turn-helix (HTH) motifs, except that in the POUs domain, the first helix and the linker to the second helix of the motif are extended. The conserved structural features have been used to propose a plausible model for DNA binding by the POUs domain. A human dwarfism mutation that affects positive control in the related POU domain protein Pit-1 maps to the same region of the HTH motif as do positive control mutations in lambda repressor.
