What's a GeneRIF?

Data suggest that Clock1a coordinates mesoderm development and primitive hematopoiesis in embryos by up-regulating Nodal-Smad3 signaling; Clock1a alterations produce embryonic defects with shortened body length, lack of ventral tail fin, or partial defect of the eyes; Clock1a activates Smad3a promoter via its E-box1 element. (Clock1a = clock circadian regulator a; Nodal = nodal modulator 1; Smad3a = SMAD family member 3a)
Title: Clock1a affects mesoderm development and primitive hematopoiesis by regulating Nodal-Smad3 signaling in the zebrafish embryo.
Smad3 is mainly active in post-mitotic, non-proliferating cells with a role in TGF-beta control of zebrafish spinal cord development
Title: A Smad3 transgenic reporter reveals TGF-beta control of zebrafish spinal cord development.
Smad2/3 activities play important roles not only in mesendodermal development but also in neural development during early vertebrate embryogenesis
Title: Smad2/3 activities are required for induction and patterning of the neuroectoderm in zebrafish.
Nodal signaling and mesendoderm induction depend on Smad2/3 and suggest that transforming growth factor-beta signals other than Nodal also contribute to Smad2/3 signaling and embryonic patterning.
Title: smad2 and smad3 are required for mesendoderm induction by transforming growth factor-beta/nodal signals in zebrafish.
although the role of Smad proteins in mediating Nodal signaling is well-documented, the functional characterization of Ttrap provides insight into a novel Smad partner that plays an essential role in the fine-tuning of this signal transduction cascade
Title: Ttrap is an essential modulator of Smad3-dependent Nodal signaling during zebrafish gastrulation and left-right axis determination.

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.
