Abstract
Mammalian SLURP1 and SLURP2 belong to the Ly-6/uPAR superfamily and are involved in maintaining the physiological integrity of keratinocytes. However, the developmental expression and functions of other Ly-6/uPAR family genes in vertebrates are still obscure. We have isolated novel Ly-6/uPAR family genes slurp-like1 (ly2.3/ly97.3) and slurp-like2 (ly2.2/ly97.2) in zebrafish. Both the Slurp-like1 and Slurp-like2 proteins contain the typical signal sequence and carboxy-terminal CCXXXXCN (X: an arbitrary amino acid) consensus sequence of the Ly-6/uPAR family but lack a transmembrane domain and a GPI-anchoring signal sequence, suggesting that both proteins may function as secretory proteins. Whole-mount in situ hybridization analysis revealed that slurp-like1 was predominantly expressed in the floor plate of the neural tube and in the hypochord of the notochord at 24 h post-fertilization (hpf) and detected in the liver and intestinal bulb at 72 hpf, while slurp-like2 was expressed in the midbrain and hindbrain at 24 hpf and detected in the liver and pancreas at 72 hpf. Differential expression profiles of the slurp-like1 and slurp-like2 genes suggest the distinct physiological involvement of these genes in zebrafish early embryogenesis.
