Summary: Enables promoter-specific chromatin binding activity. Involved in positive regulation of gene expression. Acts upstream of or within several processes, including cranial suture morphogenesis; dentinogenesis; and osteoblast differentiation. Is expressed in several structures, including bone element; ectoderm; fin; head; and optic primordium. Human ortholog(s) of this gene implicated in osteogenesis imperfecta type 12. Orthologous to human SP7 (Sp7 transcription factor). [provided by Alliance of Genome Resources, Nov 2024]

What's a GeneRIF?

cell transfection experiments demonstrated that Sp7 directly regulates the expression of dlx2b and bglap through Sp7-binding sites on the promoter regions of these two genes. Overall, this study provides new insight into the role of Sp7 in bone mineralization and tooth development.
Title: Sp7/osterix positively regulates dlx2b and bglap to affect tooth development and bone mineralization in zebrafish larvae.
In zebrafish lacking sp7, attachment bone is never present, independent of the stage of tooth development or fish age, yet replacement is not interrupted. There was abnormal orientation of teeth, and abnormal connection of pulp cavities of predecessor and replacement teeth, arrested dentinogenesis, non-polarization of odontoblasts and only a thin layer of dentin deposition.
Title: Zebrafish sp7 mutants show tooth cycling independent of attachment, eruption and poor differentiation of teeth.
Sp7 plays a critical role in limiting the level of signaling and the rate of bone growth
Title: Osterix/Sp7 limits cranial bone initiation sites and is required for formation of sutures.
FGF and Wnt/beta-Catenin pathways act in part by directing transcription of osx to promote osteoblast differentiation at sites of bone formation.
Title: Expression of osterix Is Regulated by FGF and Wnt/β-Catenin Signalling during Osteoblast Differentiation.
Data show the endogenous sp7 gene expression in the otic placode and vesicle, and in forming skeletal structures in Tg(sp7:EGFP)b1212 line.
Title: Zebrafish sp7:EGFP: a transgenic for studying otic vesicle formation, skeletogenesis, and bone regeneration.

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.
