Identification of a Specific Translational Machinery via TCTP-EF1A2 Interaction Regulating NF1-associated Tumor Growth by Affinity Purification and Data-independent Mass Spectrometry Acquisition (AP-DIA).

ABSTRACT: Neurofibromatosis type 1 (NF1) is an autosomal dominant disease that predisposes individuals to developing benign neurofibromas and malignant peripheral nerve sheath tumors (MPNST). The mechanism of NF1-tumorigenesis or the curatives have not been established. Using unique trascriptome and proteome integration method, iPEACH (1), we previously identified translationally controlled tumor protein (TCTP) as a novel biological target for NF1-associated tumors (2). Here, we identified specific TCTP-interacting proteins by sequential affinity purification and data-independent mass spectrometry acquisition (AP-DIA/SWATH) to investigate the role of TCTP in NF1-associated malignant tumors. TCTP mainly interacts with proteins related to protein synthesis and especially to elongation factor complex c
