spd-3 is a novel gene with putative transmembrane domains and predicted coiled coils. (A) spd-3 is equivalent to the novel gene H34C03.1. The oj35 allele contains a single-base-pair change in the third exon. The ok1817 deletion allele removes the 5′-UTR through exon 3 of the spd-3 gene. (B) The predicted gene product contains two putative transmembrane domains and predicted coiled coils. (C) The y-axis represents the probability of coiled-coil conformations in the SPD-3 protein. A weak coil prediction is destroyed in the oj35 allele (arrow).
