The development of zebrafish pancreas affected by deficiency of Hedgehog signaling.
Title: The development of zebrafish pancreas affected by deficiency of Hedgehog signaling.
Our study implicates PDE4 as a target for Hh inhibition, suggests an improved strategy for Hh-dependent cancer therapy, and identifies a unique probe of downstream-of-Smo Hh modulation.
Title: An in vivo chemical genetic screen identifies phosphodiesterase 4 as a pharmacological target for hedgehog signaling inhibition.
The cysteine-rich SMO domain is required for signaling in response to native Hedgehog ligands, showing that it is an important regulatory module for Smo activation.

Single continuous lumen formation in the zebrafish gut is mediated by smoothened-dependent tissue remodeling.
Title: Single continuous lumen formation in the zebrafish gut is mediated by smoothened-dependent tissue remodeling.
Fine coordination of smoothened activity by the miR-30 family allows the correct specification and differentiation of distinct muscle cell types during zebrafish embryonic development.
Title: The miR-30 microRNA family targets smoothened to regulate hedgehog signalling in zebrafish early muscle development.
These data indicate that the extracellular domain, previously thought to be dispensable for vertebrate Smoothened function, both regulates Smo ciliary localization and is essential for high-level Hedgehog signaling.
Title: The extracellular domain of Smoothened regulates ciliary localization and is required for high-level Hh signaling.
neither maternal nor zygotic Smo is required for PGC migration in zebrafish embryo. Cyclopamine instead acts independently of Smo to decrease motility of PGCs, in part by dysregulating cell adhesion and uncoupling cell polarization and translocation.
Title: Germ cell migration in zebrafish is cyclopamine-sensitive but Smoothened-independent.
Data suggest that a G protein-coupled receptor kinase, perhaps GRK2 or 3, functions as a vertebrate kinase for Smoothened, promoting Hedgehog signal transduction during early development.
Title: Smoothened signaling in vertebrates is facilitated by a G protein-coupled receptor kinase.
Hhip regulates muscle development both by sequestering Hedgehog and by modulating localization of Smoothened
Title: Hhip regulates zebrafish muscle development by both sequestering Hedgehog and modulating localization of Smoothened.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
