Across TCGA pan-cancer cohorts, TAPBPL mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated TAPBPL data layer compared with 24 for mass-spec protein and 1 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher TAPBPL mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated TAPBPL expression acts as an unfavorable survival marker, although some lineages such as PDAC show a favorable association.
CCRCC, PDAC, and LUAD are the cancer types where TAPBPL mass-spec protein most reproducibly stratifies survival.
