PIP4K2B and breast neoplasm: The sensitivity and specificity were estimated for this 10‐protein panel in an independent, comprehensive breast tumor proteome dataset [26] using the AUC scores and the results strongly support our evidence that eight of the proteins (AGR3, BCAM, CELSR1, MIEN1, NAT1, PIP4K2B, SEC23B, and THTPA) might serve as biomarkers for stratification of luminal, Her 2 and TNBC tumor subtypes.
