| Tissue Specificity | Expressed the totipotent and pluripotent stem cells of the pregastrulation embryo. Also expressed in primordial germ cells and in the female germ line. Absent from adult tissues. |
| Post Translational Modifications | Sumoylation enhances the protein stability, DNA binding and transactivation activity. Sumoylation is required for enhanced YES1 expression. Ubiquitinated.undergoes 'Lys-63'-linked polyubiquitination by WWP2 leading to proteasomal degradation. ERK1/2-mediated phosphorylation at Ser-106 promotes nuclear exclusion and proteasomal degradation. Phosphorylation at Thr-228 and Ser-229 decrease DNA-binding and alters ability to activate transcription. JNK1/2-mediated phosphorylation at Ser-347 promotes proteasomal degradation. |
| Function | Transcription factor that binds to the octamer motif (5'-ATTTGCAT-3'). Forms a trimeric complex with SOX2 or SOX15 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. |
