Induces growth and cell cycle arrests at the G1 phase of the cell cycle. Proposed core component of the chromatin remodeling INO80 complex which is involved in transcriptional regulation, DNA replication and probably DNA repair. Component of the chromatin remodeling INO80 complex; specifically part of a complex module associated with the helicase ATP-binding and the helicase C-terminal domain of INO80. Interacts with RP9. Truncated N-terminus.
