General Information

Term

nucleosome array spacer activity

ID (Ontology)

GO:0140750 (Gene Ontology)

Definition

A histone octamer slider activity that spaces nucleosomes along chromosomal DNA. This activity is involved in assembling chromatin in uniform nucleosome arrays to regulate transcription by RNA polymerases I, II, and III, as well as DNA replication, recombination and repair.[ PubMed:11683384 PubMed:16468993 ]

Also Known As
