RAB21

Across TCGA pan-cancer cohorts, RAB21 mass-spec protein differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of RAB21’s most consistent transcriptional readouts.

The strongest signal is observed in colon adenocarcinoma (COAD), where RAB21 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types RAB21 is over-expressed in tumor.

COAD, LSCC, and HNSC are the cancer types where RAB21 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 RAB21 mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
