AATF interactome in human Kms27 cells
Ontology highlight
ABSTRACT: Multiple myeloma is a hematological neoplasm of plasma cells characterized by an abnormal production of immunoglobulins. Che-1/AATF (Che-1) is an RNA binding protein involved in transcription regulation and highly expressed in this malignancy. In order to better characterize its functions in this type of disease, we performed co-immunoprecipitation experiments coupled with a mass-spec analysis by using total MM Kms27 cell lysates. From this analysis we were able to identify more than 600 proteins significantly enriched in Che-1 precipitates. As expected from its role in ribosomal RNA maturation, the Che-1 interactome contains numerous proteins involved in pre-rRNA processing and several ribosomal proteins. Notably, among other proteins interacting with Che-1, we identified many essential components of the paraspeckle which play an important role in the regulation of gene expression.
