This family consists of several eukaryotic Sin3 associated polypeptide p18 (SAP18) sequences. SAP18 is known to be a component of the Sin3-containing complex which is responsible for the repression of transcription via the modification of histone polypeptides. SAP18 is also present in the ASAP complex which is thought to be involved in the regulation of splicing during the execution of programmed cell death. Length = 121 |
