Summary: Enables DNA-binding transcription activator activity, RNA polymerase II-specific and bHLH transcription factor binding activity. Contributes to E-box binding activity. Involved in positive regulation of transcription by RNA polymerase II. Located in nucleus. Part of transcription regulator complex. [provided by Alliance of Genome Resources, Dec 2024]
Annotation information: Note: In the NCBI Build GRCh37 reference assembly SCXA and SCXB are duplicate genes in close proximity to each other on chromosome 8. In August, 2010 the Genome Reference Consortium determined that the region contains a duplication error. The clone on which SCXA was based (AC110280.8) was be removed from the GRCh38 reference assembly and SCXB was retained and renamed to SCX. [27 Sep 2015]
Expression: Ubiquitous expression in appendix (RPKM 1.6), prostate (RPKM 1.6) and 25 other tissues See more

The transcription factor scleraxis is an important inducer of extracellular matrix gene expression in the heart that also control MMP2 expression. The scleraxis can exert control over both extracellular matrix synthesis and breakdown, and thus may contribute to matrix remodeling in wound healing and disease.

Abnormal upregulation of HIF-2alpha served as a key switch to direct TSPCs differentiation into osteochondral-lineage rather than teno-lineage. Notably, Scleraxis (Scx), an essential tendon specific transcription factor, was suppressed on constitutive activation of HIF-2alpha and mediated the effect of HIF-2alpha on TSPCs fate decision.

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.
