CC -!- FUNCTION: Catalytic component of the ISW2 complex, which acts in
CC remodeling the chromatin by catalyzing an ATP-dependent alteration in
CC the structure of nucleosomal DNA. The ISW2 complex is involved in
CC coordinating transcriptional repression and in inheritance of telomeric
CC silencing. It is involved in repression of MAT a-specific genes, INO1,
CC and early meiotic genes during mitotic growth dependent upon
CC transcription factor UME6 and in a parallel pathway to the RPD3-SIN3
CC histone deacetylase complex. {ECO:0000269|PubMed:10090725,

CC ECO:0000269|PubMed:11533234, ECO:0000269|PubMed:14673157}.
CC -!- SUBUNIT: Component of the ISW2 complex, which at least consists of
CC ISW2, ITC1, DLS1 and DPB4. May form a stable subcomplex with ITC1.

CC -!- INTERACTION:
CC Q08773; P53125: ITC1; NbExp=2; IntAct=EBI-31118, EBI-23967;
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00624,
CC ECO:0000269|PubMed:14562095}.
CC -!- MISCELLANEOUS: Present with 1520 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the SNF2/RAD54 helicase family. ISWI subfamily.
CC {ECO:0000305}.
