PCBP4

Across TCGA patient cohorts, PCBP4 protein abundance is significantly associated with the protein abundance of many other proteins, with 17,756 significant associations in total. LUAD shows the largest number of these associations.

The most reproducible PCBP4-associated proteins across cancer lineages are MEX3A, CDC34, and AHNAK_S5298. Each is linked with PCBP4 in more than 3 cancer types. Because this analysis shows association rather than direction, both PCBP4-to-partner and partner-to-PCBP4 results are reported.

Each partner links to its own Q-omics profile. The scatter plot shows the strongest example, PCBP4 versus MEX3A in UCEC, with a Pearson correlation of 0.32.

protein abundance associated proteins by consensus

Ranked by combined sampling and lineage consensus. X-score (PCBP4→partner) and Y-score (partner→PCBP4) are standardized regression coefficients; both directions are reported because the association is undirected. p-values are from the association test.

Lineage	Partner protein	X-score	Y-score	p(X)	p(Y)	Sampling consensus	Lineage consensus
UCEC	MEX3A →	+0.596	+0.422	.002	.001	3	4
LUAD	CDC34 →	+0.352	+0.534	<.001	<.001	3	3
