    SUBCELLULAR LOCALIZATION     intracellular
  • POU2F1 colocalizes with lamin B1 at the spindle poles and midbody
  • basic FUNCTION
  • transcription factor for small nuclear RNA and histone H2B genes
  • involved in the transcriptional repression of the gonadotropin-releasing hormone receptor gene(GNRHR)
  • repressing with its POU domain, the expression of E-selectin, vascular cell adhesion molecule (VCAM-1), two cytokine-inducible, NF-kappaB-dependent endothelial-leukocyte adhesion molecules that participate in the leukocyte recruitment phase of the inflammatory response
  • transactivating PTTG1 (Zhou 2008)
  • downstream effector of Notch signaling during radial glia formation (Kiyota 2008)
  • may have regulatory functions in prostate development and cancer progression (Jariwala 2009)
  • is phosphorylated in response to oxidative and genotoxic stress and is essential for a normal post-stress transcriptional response (Kang 2009)
  • POU2AF1 together with POU2F1/POU5F1, binds to octamer sites in promoters and enhancers to activate transcription of immunoglobulin (Ig) genes
  • a putative defect in POU2F1 and/or POU2F2, by affecting HMGA1 expression, may cause INSR dysfunction, leading to defects of the INSR signaling pathway
  • new role for POU2F1 in mesenchymal stem cells (hMSCs) aging
  • POU2F1 and POU2AF1 are selectively required for the in vivo generation of CD4(+) memory T cells
  • POU2F1 and GATA3/POU2F2 direct Th2 cytokine gene expression in a cooperative manner
  • plays a critical role in CD4 T cells through regulating gene expression during differentiation and mediating long-range chromosomal interactions
  • has various functions in gene regulation
  • participates in carcinogenesis and cancer progression via promotion of cell proliferation and metastasis
  • is a DNA-binding transcription regulator and its level being highly increased in many human cancers
  • CELLULAR PROCESS nucleotide, transcription, regulation

  • interacting with p65
  • interacting with NR3C1, AR, PGR, HCFC1
  • interact with glycolytic enzymes in a complex which may act as a metabolic sensor (Shakya 2009)
  • POU2AF1 is a B lymphocyte-specific transcription factor which coactivates POU2F1 and POU2F2 on B cell specific promoters
  • PDCD1LG2 expression is regulated by two different promoters that function in a lineage-specific manner, with the B-1-specific promoter being constitutively active as a result of POU2F1 and POU2F2 binding
  • POU2F1 cooperates with the TATA binding initiation complex to control rapid transcription of NOS2
  • acts as a transcriptional repressor of CRP expression
  • POU2F1 integrates metabolic and stress signals via OGT modification to regulate target gene activity
  • POU2F1 regulates IL17A expression by directing interchromosomal associations in conjunction with CTCF in T cells
  • STAT2 and STAT4 are direct targets for POU2F1 protein
  • POU2F1 induced the expression of TWIST1, SNAI1, SNAI2 and ZEB1 genes which are involved in the regulation of epithelial-to-mesenchymal transition (EMT)
  • dynamic interplay between POU2F1 and POU2F5, in particular during the critical window immediately after loss of pluripotency when cells make the earliest developmental fate decisions
  • BRCA1 promotes oxidative metabolism by degrading POU2F1, a transcription factor with proglycolytic and tumorigenic effects.
