RAB1B

Across TCGA pan-cancer cohorts, RAB1B mass-spec protein differs between tumor and matched normal tissue in 6 of 18 cancer types tested, making tumor–normal expression one of RAB1B’s most consistent transcriptional readouts.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where RAB1B mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types RAB1B is over-expressed in tumor, although a few such as HNSC and COAD show the opposite, repressed pattern.

HNSC, COAD, and CCRCC are the cancer types where RAB1B 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 RAB1B mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
