Fig. S2 Loss of maternal furinA does not enhance jaw defects in furinA mutants. (A) Temporal expression profiles of furinA and edn1 were determined by RT-PCR. The zebrafish ornithinedecarboxylase (odc) gene was used as an internal PCR control. The following primer pairs were used: furinA, 5′AGCGGAGGCGTCAATGA3′/5′TGAGCACGGCCACAATGGCAG3′ (1138 bp); edn1, 5′CCTGAAATGCATGACGTGTG3′/5′AATACGGGACTTGCATACTACA3′ (659 bp); and odc, 52ACACTATGACGGCTTGCACCG3′/5′CCCACTGACTGCACGATCTGG3′ (309 bp). (B) Loss of maternal furinA alone yields only phenotypically wild-type larvae. Loss of both maternal and zygotic furinA does not enhance joint loss phenotype over loss of zygotic furinA alone. M, maternal; Z, zygotic.
