The breast cancer STRING network where Chi Square χ² ≥ 15 from fully tryptic phospho peptides. Breast cancer TRYP STYP, frequency difference greater than 15 and χ² value greater than 15 at degrees of freedom of 1 (p < 0.0001). Network Information: number of nodes, 191; number of edges, 182; average node degree, 1.91; avg. local clustering coefficient, 0.335; expected number of edges, 152; PPI enrichment p-value, 0.00911
