Updated project metadata. Updated publication reference for PubMed record(s): 29986055. The study deals with the elucidation of potential interaction partners of the intracellular domain of the transmembrane receptor Notch1, termed NICD. The NICD is released from the cytoplasmic tail of the Notch receptor by gamma-secretase treatment and translocated as a transcription factor to the nucleus. Here, virally transduced recombinant NICD constructs (wild-type and deltaEP hyperactive mutant) were employed for AP-MS with the aim of identifying novel NICD interactors in a murine T cell leukemia cell line.
