Full proteome analysis of Hoxb8 immortalized murine myeloid progenitors knockout for CCDC134 and differentiated into macrophages
Ontology highlight
ABSTRACT: We recently identified CCDC134 as a novel regulator of TLR responses. To gain a comprehensive understanding of the effects of CCDC134 loss, we conducted total proteome analysis on control sgRen and sgCCDC134 Hoxb8 immortalized murine myeloid progenitors that were differentiated into macrophages. Interestingly, we observed that plasma membrane and endolysosomal TLRs, along with their associated chaperone Gp96, were among the most significantly downregulated proteins. Our findings further demonstrated that CCDC134 is essential for the proper folding and stability of Gp96. As a result, the deletion of CCDC134 in various cell lines and Hoxb8-derived macrophages results in altered TLR folding and trafficking.
