SepN genomic structure and morpholino inhibition of SepN expression. (a) Genomic structure of the zebrafish sepN locus containing conserved elements including a selenocysteine codon (Sec), a Sec Redefinition Element (SRE), and a selenocysteine insertion sequence (SECIS) element. * indicates stop codon; red bars indicate sbMOs; arrows indicate primers used to detect sepN transcripts by RT-PCR. (b) RT-PCR analysis of sepN transcripts in 24 hpf WT, MO1- or MO2-injected embryos. *,WT sepN amplicon; arrows, intron-included amplicons; m, markers. (c and d) sepN RNA levels are reduced in MO1-injected embryos. Lateral views with rostral left. |
