RAP1A

Across TCGA pan-cancer cohorts, RAP1A mass-spec protein differs between tumor and matched normal tissue in 6 of 18 cancer types tested, making tumor–normal expression one of RAP1A’s most consistent transcriptional readouts.

The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where RAP1A mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types RAP1A is over-expressed in tumor, although a few such as CCRCC and COAD show the opposite, repressed pattern.

CCRCC, COAD, and HNSC are the cancer types where RAP1A 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 RAP1A mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
