A BRCA1-retrieved HPD pathway-protein association matrix. The matrix shows few HPD pathways involving the query protein BRCA1 (on the y-axis) against pathway molecular components (on the x-axis). A red cell in the matrix indicate that the molecular entity is present in the pathway, whereas a white cell in the matrix indicate that the molecular entity is absent from the pathway. Only few HPD pathways are shown. These BRCA1-retrieved pathways are sorted by their shared protein counts among all pairwise pathway comparisons in these pathways.
