Figure 6. Identification of planarian COMPASS proteins. (A) Human COMPASS and COMPASS-like complexes. SET1/MLL family members (shown in gray) act in complex with other proteins. Core subunits common to all COMPASS and COMPASS-like complexes are shown in dark blue. Complex-specific subunits are color-coded by complex: red, SET1/COMPASS complex; orange, SET1/COMPASS and MLL1/2 COMPASS-like complexes; green, MLL1/2 COMPASS-like complex; light blue, MLL3/4 COMPASS-like complex. (B) S. mediterranea homologs of COMPASS proteins. Color-coding matches that in A. e-values are for reciprocal protein blast of the predicted full-length planarian protein against the top human hit in the NCBI non-redundant protein sequence database.
