Fig. 1. Medaka smp belongs to a novel family of vertebrate genes.
(A) Smp bears two highly conserved regions (HRI and HRII), two 14-3-3
consensus-binding domains and a nuclear-localization signal (NLS). (B)
A phylogenetic tree of the smp family showing two smp
groups: A and B. Hs, Homo sapiens; Mm, Mus musculus; Gg,
Gallus gallus; Xl, Xenopus laevis; Dr, Danio rerio;
Fr, Fugu rubripes; Tn, Tetraodon negroviridis; Ol,
Oryzias latipes. (C) Western blot after co-immunoprecipitation of
14-3-3 or SKIIP with Ol-Smp and FAM53B. Co-immunoprecipitation reveals an
interaction of SKIIP with human FAM53B, but not with Ol-Smp.
