Summary: Enables N-acetylgalactosaminyl-proteoglycan 3-beta-glucuronosyltransferase activity and glucuronosyl-N-acetylgalactosaminyl-proteoglycan 4-beta-N-acetylgalactosaminyltransferase activity. Involved in chondroitin sulfate biosynthetic process. Acts upstream of or within several processes, including positive regulation of smoothened signaling pathway; skeletal system development; and sulfation. Is active in Golgi apparatus. Is expressed in several structures, including alimentary system; brain; ear; respiratory system; and skeletal system. Human ortholog(s) of this gene implicated in temtamy preaxial brachydactyly syndrome. Orthologous to human CHSY1 (chondroitin sulfate synthase 1). [provided by Alliance of Genome Resources, Dec 2024]

We showed the spatial and temporal expression of Skt gene in the cloacal plate formation. This gene could be a marker for the cloacal plate during the anorectal development. Skt was considered to be associated with the embryogenesis of ARMs.
Title: The Skt gene, required for anorectal development, is a candidate for a molecular marker of the cloacal plate.
Chondroitin sulfate (CS) modification of proteins by CHSY1 appears critical for proper regulation of immune cells of the myeloid lineage and for maintaining the integrity of neuronal tissues, since a defect in this gene results in increased inflammation and abnormal phenotypes associated with age-related diseases.
Title: Loss of Chondroitin Sulfate Modification Causes Inflammation and Neurodegeneration in skt Mice.
Data indicate a phosphorylated tetrasaccharide linkage structure, GlcUAbeta1-3Galbeta1-3Galbeta1-4Xyl(2-O-phosphate), in chondroitin N-acetylgalactosaminyltransferase-1 knockout ChGn-1(-/-) growth plate cartilage.
Title: GlcUAβ1-3Galβ1-3Galβ1-4Xyl(2-O-phosphate) is the preferred substrate for chondroitin N-acetylgalactosaminyltransferase-1.
The results showed that Chsy1 is an essential regulator of joint patterning and provide a mouse model of human brachydactylies caused by mutations in CHSY1.
Title: Chondroitin sulfate synthase 1 (Chsy1) is required for bone development and digit patterning.

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.
