Figure 3. pic−/− encodes a PAPS transporter.

Figure 3

Genetic map of pic locus (A). Note that z1534 has not been assigned a genetic position as it was found on the RH map. Allele sequencing identifies picto216z as a premature stop codon in exon 3 and picto14mx as a deletion of exon 3 (B). Zebrafish PAPST1 clusters with human and Drosophila PAPST1 in a dendrogram (C). Expression of wild-type PAPST1 in a single notochord cell rescues synthesis of KS in pic−/− larvae (D–E). Close-up of single cell secreting KS in brown (arrow in E), and the same cell counterstained for the rescue construct reporter in purple (arrow in F). The dendrogram was made using Clustal W and Treeview68k. Accession numbers: AB107958, NP_648954, AB106538, NP_057032, NP_991198, NP_001035084, NM_005827. Zebrafish and human PAPST1 share 70% amino acid identity. Panel D scale bar = 100μM. Panel E scale bar = 50μM.
