cistrome

In simple words, the cistrome refers a collection of regulatory elements of a set of genes, including transcription factor binding sites and histone modifications. More specifically, "the set of cis-acting targets of a trans-acting factor on a genome-wide scale, also known as the in vivo genome-wide location of transcription factor binding sites or histone modifications".{{cite journal | vauthors = Liu T, Ortiz JA, Taing L, Meyer CA, Lee B, Zhang Y, Shin H, Wong SS, Ma J, Lei Y, Pape UJ, Poidinger M, Chen Y, Yeung K, Brown M, Turpaz Y, Liu XS | title = Cistrome: an integrative platform for transcriptional regulation studies | journal = Genome Biol. | volume = 12 | issue = 8 | pages = R83 | year = 2011 | pmid = 21859476 | pmc = 3245621 | doi = 10.1186/gb-2011-12-8-r83 | doi-access = free }} The term cistrome is a portmanteau of {{langr|mis|cistr}} (from cistron) + ome (from genome). The term cistrome was coined by investigators at the Dana–Farber Cancer Institute and Harvard Medical School.{{cite web | url = http://cistrome.pbworks.com/w/page/10521472/FrontPage | title = cistrome / FrontPage | publisher = PBWiki, Inc. }}

Technologies such as chromatin immunoprecipitation combined with microarray analysis "ChIP-on-chip" or with massively parallel DNA sequencing "ChIP-Seq" have greatly facilitated the definition of the cistrome of transcription factors and other chromatin associated proteins.
