+We are pleased to announce two new ENCODE 3 transcription factor binding site tracks for human +(GRCh37/hg19, GRCh38/hg38) assemblies. These tracks show regions of transcription factor binding +derived from a large collection of ChIP-seq experiments performed by the ENCODE project between +February 2011 and November 2018. +
+
+The ENCODE TF ChIP-seq data were processed using the
+ENCODE Transcription Factor ChIP-seq Processing
+Pipeline to generate peaks of TF binding. Peaks from 1264 experiments (1256 in hg38) representing
+338 transcription factors (340 in hg38) in 130 cell types (129 in hg38) were compiled in order to
+generate these two tracks. The peaks were grouped together to produce a summary display showing
+occupancy regions for each factor, seen here in the TF ChIP Clusters tracks:
+hg19,
+hg38
+The underlying ChIP-seq peak data are available from the ENCODE 3 TF ChIP Peaks tracks:
+hg19,
+hg38
+
+Thanks to the ENCODE Consortium, +the ENCODE ChIP-seq production laboratories, and the ENCODE Data Coordination Center for generating +and processing the TF ChIP-seq datasets used here. The ENCODE accession numbers of the constituent +datasets are available from the peak details page. Special thanks to Henry Pratt, Jill Moore, +Michael Purcaro, and Zhiping Weng, PI, at the +ENCODE Data Analysis Center (ZLab at UMass Medical Center) +for providing the peak datasets, metadata, and guidance developing this track. Thanks to Kate +Rosenbloom and Conner Powell of the UCSC Genome Browser group for their work in creating and +releasing these tracks. +
+A genome browser is now available for the Chinese Hamster Ovary cell line assembly released in June 2017 by the Eagle Genomics Ltd (CHOK1S_HZDv1).
