CC -!- FUNCTION: Required for the maintenance of pluripotency and self-renewal
CC of embryonic stem cells. Transcriptional activator that binds the DNA
CC consensus sequence 5'-ATGCAAAT-3'. {ECO:0000269|PubMed:17827181}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:25846318}.
CC -!- DEVELOPMENTAL STAGE: Widely expressed during embryonic development (at
CC protein level). In pre-primitive streak stage embryos, expressed in the
CC epiblast and in a salt-and-pepper fashion in the forming hypoblast
CC (stages XI and XIII) (at protein level). As the primitive streak starts
CC to form, strongly expressed in the epiblast of the streak itself (stage
CC XIV) and in the mesoderm emerging from it, whereas expression in the
CC lower layer tends to decrease (stages 2 through 4+). Expression in the
CC area opaca is lost by stage 3+. At later stages, continues to be
CC expressed in the mesoderm, but not detected in the endoderm (stages 5
CC through 8). At stage 5, expressed in all cells of the germinal
CC crescent. At stage 8 and subsequently, strongly expressed in the neural
CC plate and neural tube with particularly strong expression in the
CC anterior hindbrain/posterior midbrain. At stage 9 and subsequently,
CC still expressed in neural tissue and in primordial germ cells (at
CC protein level). At stage 33, still expressed in germ cells. At stages
CC 42-43, expressed in male and female gonads, as well as in spleen and
CC brain, but at much lower levels than in proliferating embryonic stem
CC cells. {ECO:0000269|PubMed:17827181, ECO:0000269|PubMed:25846318}.
CC -!- INDUCTION: Strongly down-regulated during embryonic stem cell
CC differentiation induced either by retinoic acid treatment, or by cell
CC adhesion prevention leading to embryoid body formation.
CC {ECO:0000269|PubMed:17827181}.
CC -!- SIMILARITY: Belongs to the POU transcription factor family.
CC {ECO:0000255|RuleBase:RU361194}.
