Figure 1. Five pharyngeal clusters. Pie charts of protein categories for all candidate pharyngeal genes (A) and individual clusters (B to E). GST, glutathione S-transferase; ECM, extracellular matrix protein; Prot. Inh., protease inhibitor; ShTK, ShTK domain-containing protein; Chan./Recep., channel molecule or receptor; Cytosk./Musc., cytoskeleton or muscle protein; Enzyme, metabolism enzyme; DUF139, domain of unknown function 139 domain; Trnx Factor, transcription factor; and Kin./Phos., kinase or phosphatase. (F to J) Previously uncharacterized genes were expressed as predicted. C49G7.4 in Ph-G, confirmed by co-staining with a gland-specific antibody, J126 (19), M03D4.4 in Ph-M, F21D5.9 in embryonic Epi, ZK1067.7 in late muscles and marginal cells from Topo Mounts 14 or 29 (Ph-MMC) (9), and C15H9.9 in Ph-MC. Dotted lines indicate the pharynx [(F) to (J)].
