CKAP4

Across TCGA pan-cancer cohorts, CKAP4 mass-spec protein differs between tumor and matched normal tissue in 6 of 18 cancer types tested, making tumor–normal expression one of CKAP4’s most consistent transcriptional readouts.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where CKAP4 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types CKAP4 is over-expressed in tumor.

HNSC, CCRCC, and LSCC are the cancer types where CKAP4 tumor–normal differential expression is most reproducible.

mass-spec protein tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in CKAP4 mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
