The secretion of CKAP4-containing exosomes was mediated by DKK1-dependent endocytosis routes and required exosome biogenesis molecules. The serum CKAP4 levels were higher in patients with PDAC than healthy control individuals.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
