Supplementary information

Oct-1 also known as POU domain class 2 transcription factor 1 (POU2F1) is a transcription factor characterized by its POU-specific domain. The molecular weight of Oct-1 is approximately 76 kDa. It is expressed widely across different tissues with high levels found in lymphoid organs and epithelial cells. It binds to octamer motifs in the promoters of target genes regulating their transcription. Oct-1 plays a role in the cell cycle development and immune response.
Biological function summary

Oct-1 participates in the regulation of gene expression by influencing RNA polymerase II. It is not part of a larger protein complex for its primary function but it does interact with other cofactors. Oct-1 is essential for maintaining the expression of housekeeping genes as well as for the induction of specific genes during external stimuli responses. By modulating cellular responses Oct-1 helps in the regulation of cells' growth differentiation and adaptation to stress.

Pathways

Oct-1 is involved in pathways related to stress responses and immune system function. It significantly influences the transcriptional activation of genes associated with the stress response pathway. Oct-1 associates with proteins like c-Myc and others within these pathways which contribute to the regulation of cell proliferation and apoptosis. Its role in these pathways highlights its involvement in cellular homeostasis and survival.

Oct-1's dysregulation connects to the pathogenesis of various conditions including cancer and autoimmune diseases. Changes in Oct-1 activity have been observed in several cancers affecting tumorigenesis and progression. It interacts with proteins like Bcl-2 in the context of cancer impacting cell survival mechanisms. In autoimmune diseases such as lupus altered Oct-1 function can lead to inappropriate immune responses partly through interaction with transcription factors like NF-κB. Understanding the role of Oct-1 can help in developing targeted therapeutic strategies for these disorders.

Target data

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.. (Microbial infection) 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.
