TCHP and cancer: Other notable predicted SLiM candidates include phosphatase docking motifs (DOC_PP1_RVXF_1) and SLiMs that mediate interactions with tumor suppressor proteins such as breast cancer type 1 susceptibility protein (LIG_BRCT_BRCA1_1) and retinoblastoma protein (LIG_Rb_LxCxE_1), as well as other proteins important in the regulation of cell growth and division (LIG_HCF-1_HBM_1).
