Protein function

Transcription factor that binds to the octamer motif (5′-ATTTGCAT-3′). Forms a trimeric complex with SOX2 on DNA and controls the expression of a number of genes involved in embryonic development such as YES1, FGF4, UTF1 and ZFP206. Critical for early embryogenesis and for embryonic stem cell pluripotency.

Protein tissue specificity

Expressed in developing brain. Highest levels found in specific cell layers of the cortex, the olfactory bulb, the hippocampus and the cerebellum. Low levels of expression in adult tissues.

Protein sequence and domain

The POU-specific domain mediates interaction with PKM.Belongs to the POU transcription factor family. Class-5 subfamily.; Contains 1 homeobox DNA-binding domain.; Contains 1 POU-specific domain.

Protein post-translational modifications

Sumoylation enhances the protein stability, DNA binding and transactivation activity. Sumoylation is required for enhanced YES1 expression (By similarity).; Ubiquitinated; undergoes ‘Lys-63’-linked polyubiquitination by WWP2 leading to proteasomal degradation.; ERK1/2-mediated phosphorylation at Ser-111 promotes nuclear exclusion and proteasomal degradation. Phosphorylation at Thr-235 and Ser-236 decrease DNA-binding and alters ability to activate transcription.

Protein cellular localization

Cytoplasm. Nucleus. Note: Expressed in a diffuse and slightly punctuate pattern.


This gene encodes a transcription factor containing a POU homeodomain that plays a key role in embryonic development and stem cell pluripotency. Aberrant expression of this gene in adult tissues is associated with tumorigenesis. This gene can participate in a translocation with the Ewing’s sarcoma gene on chromosome 21, which also leads to tumor formation. Alternative splicing, as well as usage of alternative AUG and non-AUG translation initiation codons, results in multiple isoforms. One of the AUG start codons is polymorphic in human populations. Related pseudogenes have been identified on chromosomes 1, 3, 8, 10, and 12.
