RNA-binding proteins mind the GAPs

Nature Immunology volume 18, pages 146–148 (2017)Cite this article

Subjects

Increased expression of the ubiquitin ligase TRAF6 in hematopoietic stem cells promotes activity of the GTP-binding protein Cdc42 and consequent diminished function of hematopoietic stem cells by ubiquitination of the RNA-binding protein hnRNP-A1, which leads to an inability to properly process pre-mRNA encoding Cdc42-inhibitory GTPase-activating proteins.
