Summary
Enables transforming growth factor beta binding activity. Involved in several processes, including cholesterol efflux; cholesterol homeostasis; and nervous system development. Acts upstream of or within several processes, including ciliary body morphogenesis; negative regulation of Wnt signaling pathway; and telencephalon development. Located in extracellular space. Is expressed in embryo and olfactory epithelium. Orthologous to human TSKU (tsukushi, small leucine rich proteoglycan). [provided by Alliance of Genome Resources, Apr 2022]
Expression
Broad expression in bladder adult (RPKM 55.7), duodenum adult (RPKM 40.7) and 19 other tissues See more

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.
