SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm
	intracellular,nucleus

basic FUNCTION	involved in the control of the forebrain development and the cell-cell signaling process underlying the hypothalamic regulation of female puberty
	playing a role in regulating transcription in a number of tissues in addition to activating immunoglobulin gene expression
	playing an essential role during the terminal phase of B cell differentiation
	with POU2F2, are B-cell associated transcription factors expressed in a subset of patients with acute myeloid leukemia (AML)
	POU2AF1 together with POU2F1/POU2F2, binds to octamer sites in promoters and enhancers to activate transcription of immunoglobulin (Ig) genes
	POU2F1 and GATA3/POU2F2 direct Th2 cytokine gene expression in a cooperative manner

CELLULAR PROCESS	cell life, differentiation
	nucleotide, transcription, regulation

PHYSIOLOGICAL PROCESS

development

PATHWAY

metabolism

signaling

a component

INTERACTION

DNA	binding to the octamer motif ATGCAAAT

RNA

small molecule

protein	ZNF593
	repressing the involucrin promoter activity in epithelial cells and in the presence of the silencer element(when overexpressed)
	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
	a putative defect in POU2F1 and/or POU2F2, by affecting HMGA1 expression, may cause INSR dysfunction, leading to defects of the INSR signaling pathway
