Protein attributes
| Sequence length | 150 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | Involved in the tethering of the SIN3 complex to core histone proteins. Interacts with bicoid (bcd) to repress transcription of bicoid target genes in the anterior tip of the embryo; a process known as retraction. Interacts with Trl and binds to Polycomb response elements at the bithorax complex. May contribute to the regulation of other homeotic gene expressions. Ref.1 Ref.6 |
| Subunit structure | Forms a complex with SIN3 and histone deacetylase By similarity. Interacts with the N-terminal residues of TRL. Interacts with BCD; in vitro and yeast cells. Ref.1 Ref.6 |
| Subcellular location | |
| Developmental stage | Expressed both maternally and zygotically. Ref.1 |
| Sequence similarities | Belongs to the SAP18 family. |
