Structural highlights

Function

ORC1B_ARATH Essential protein required for ovules fertilization (PubMed:15634699, PubMed:19171893). Component of the origin recognition complex (ORC) that binds origins of replication. It has a role in both chromosomal replication and mating type transcriptional silencing. Binds to the ARS consensus sequence (ACS) of origins of replication (By similarity). H3K4me3 effector that regulates positively the transcription of a subset of genes (PubMed:19171893).[UniProtKB:P54784]^{[1] [2]}
