Figure 7: CD44v6 and mRNA processing. (a) Enrichment factors for some proteins engaged in RNA-related processes in CD44v6 versus CD44 coimmunoprecipitating cell lysates. (b) Reactome analysis of CD44s-associated (cells: dark red, TEX: red) and CD44v6-associated (cells: dark green, TEX: green) mRNA processing proteins grouped according to splicing, processing, transport, stabilization, and silencing or rRNA and tRNA processing is shown (full names of synonyms: Table S6). Components of the mRNA processing machinery are most abundantly associated with CD44v6. The seemingly stronger enrichment in TEX than cells would be in line with the associations being established during ILV loading.
