| Here , we report that SAP30L , a close homolog of Sin 3 associated protein 30 ( SAP 30 ) , interacts with several components of the Sin3A corepressor complex . ^^^ Finally , we characterize a functional nucleolar localization signal in SAP30L and show that SAP30L and SAP 30 are able to target Sin3A to the nucleolus . . ^^^ |
