Genome wide H3K4me2 detection after CD74 activation.. Genome wide H3K4me2 detection after CD74 activation.

CD74 (invariant chain), expressed on B cells, is directly involved in shaping the B cell repertoire by regulating their survival in health and disease. Binding of its ligand, macrophage migration inhibitory factor (MIF), induces a cascade that results in CD74 intramembrane proteolysis, and the release of the CD74 intracellular domain (CD74-ICD). CD74-ICD translocates to the nucleus where it induces activation of transcription. In the current study, we characterized the transcription factor activity of CD74-ICD. Following histone modifications we are able to characterize CD74's binding sites as regulatory areas. Overall design: Examination of the histone modifications with or without CD74 cell surface mulecule activation.
