This locus includes a subregion that was identified as a candidate cis-regulatory module (CRM) in developing mouse thymocytes based on a combination of DNase I hypersensitivity and transcription factor binding. That CRM was validated as an active enhancer by high-throughput CapStarr-seq reporter assays showing weak activity in P5424 T cells and NIH3T3 fibroblasts. This locus also includes a B cell regulatory element that was identified by FAIRE-seq (formaldehyde-assisted isolation of regulatory elements sequencing), and which was validated as an enhancer by STARR-seq (self-transcribing active regulatory region sequencing) in lipopolysaccharide-activated mouse splenic B cells.
