In module 7, RAFTK (protein tyrosine kinase 2 beta, drug target of LEF) directly interact with two GSZ targets and indirectly associate with more GSZ targets (p72-Syk, spleen tyrosine kinase; nPKC-delta, protein kinase C, delta) and RA disease genes. The gene discussed is PTK2B; the disease is rheumatoid arthritis.
