Mouse Histone deacetylase complex subunit SAP30L,SAP30L ELI

Functions as transcription repressor, probably via its interaction with histone deacetylase complexes.

Involved in the functional recruitment of the class 1 Sin3-histone deacetylase complex (HDAC) to the nucleolus.

Binds DNA, apparently without sequence-specificity, and bends bound double-stranded DNA.

Binds phosphoinositol phosphates (phosphoinositol 3-phosphate, phosphoinositol 4-phosphate and phosphoinositol 5-phosphate) via the same basic sequence motif that mediates DNA binding and nuclear import.
