General annotation (Comments)

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 By similarity.

Subunit structure

Interacts with ZSCAN10, UBE2I and PKM. Interacts with WWP2 By similarity.

Subcellular location

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

Domain

The POU-specific domain mediates interaction with PKM By similarity.

Post-translational modification

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 By similarity.

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 By similarity.

Sequence similarities

Belongs to the POU transcription factor family. Class-5 subfamily.

Contains 1 homeobox DNA-binding domain.

Contains 1 POU-specific domain.
