Sin3A-associated protein, 30kDa, also known as SAP30, is a protein which in humans is encoded by the SAP30 gene.[5]
Function
HDAC2, RbAp46, RbAp48, and other polypeptides. This complex is active in deacetylating core histone octamers, but inactive in deacetylating nucleosomal histones. A pseudogene of this gene is located on chromosome 3.[5]
Mammals have one paralog of SAP30, named SAP30-like (SAP30L), which shares 70% sequence identity with SAP30.[6] SAP30 and SAP30L together constitute a well-conserved SAP30 protein family. Also SAP30L interacts with several components of the Sin3A corepressor complex and induces transcriptional repression via recruitment of Sin3A and histone deacetylases.[7]
Proteins of the SAP30 family (SAP30 proteins) have a functional
nucleolar localization signal and they are able to target Sin3A to the nucleolus.[7] SAP30 proteins have sequence-independent contact with DNA by their N-terminal zinc-dependent module and their acidic central region contributes to histone and nucleosome interactions. The DNA binding of SAP30 proteins is regulated by the nuclear signalling lipids, phosphoinositides (PI).[8] SAP30 proteins provide the first example in which the DNA and PIs seem to stand in a mutually antagonizing interrelationship in regard to their interaction with zinc finger proteins and thus exemplifies the molecular mechanism how these lipids can contribute for gene regulation.[8][9]
