RL   Submitted (DEC-2008) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Regulator of biological processes that recruits a histone
CC       deacetylase to control gene transcription. May play a role in the entry
CC       into mitosis, negatively regulating the cell proliferation. Formation
CC       of stable complexes with geminiviridae replication-associated proteins
CC       may create a cellular environment which favors viral DNA replication
CC       (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the retinoblastoma protein (RB) family.
CC       {ECO:0000305}.
