Summary: Predicted to enable receptor antagonist activity and transforming growth factor beta binding activity. Acts upstream of or within several processes, including muscle cell development; roof of mouth development; and transforming growth factor beta receptor signaling pathway. Located in extracellular space. Is expressed in several structures, including central nervous system; genitourinary system; limb; liver; and spleen. Orthologous to human WFIKKN2 (WAP, follistatin/kazal, immunoglobulin, kunitz and netrin domain containing 2). [provided by Alliance of Genome Resources, Oct 2024]

What's a GeneRIF?

results indicate that both WFIKKN and follistatin utilize their FSDs to block the type II receptor but do so via different binding interactions.
Title: Crystal structure of the WFIKKN2 follistatin domain reveals insight into how it inhibits growth differentiation factor 8 (GDF8) and GDF11.
Taken together, this study provides evidence that GASP1 regulates CB1 receptor downregulation in vivo, and that postendocytic receptor trafficking has a key role in the development of tolerance to WIN55,212-2.
Title: Differential regulation of behavioral tolerance to WIN55,212-2 by GASP1.

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.
