Summary: Enables transforming growth factor beta binding activity. Involved in establishment of protein localization to extracellular region and secondary palate development. Acts upstream of or within negative regulation of activated T cell proliferation; negative regulation of cytokine production; and positive regulation of gene expression. Predicted to be located in cell surface and nucleoplasm. Predicted to be active in external side of plasma membrane; extracellular matrix; and extracellular space. Is expressed in several structures, including genitourinary system; jaw; lung; sensory organ; and skeletal muscle. Orthologous to human LRRC32 (leucine rich repeat containing 32).

Thrombin contributes to cancer immune evasion via proteolysis of platelet-bound GARP to activate LTGF-beta.
Title: Thrombin contributes to cancer immune evasion via proteolysis of platelet-bound GARP to activate LTGF-β.
Study demonstrated that B cells are required for the induction of oral tolerance of T cell-dependent antigens via GARP and revealed for the first time that cell surface GARP-TGF-beta is an important checkpoint for regulating B cell peripheral tolerance, highlighting a mechanism of autoimmune disease pathogenesis.
Title: B lymphocytes confer immune tolerance via cell surface GARP-TGF-β complex.
Data (including data from studies using knockout mice) suggest that Garp/Lrrc32 is involved in up-regulation of Tgfb3 and is essential for normal embryogenesis of palate; knockout of Garp causes postnatal lethality, cleft palate, and decreased apoptosis and Smad2 phosphorylation in medial edge epithelial cells of palatal shelf of embryos. (Tgfb3 = transforming growth factor beta 3; Smad2 = MAD homolog protein 2)
Title: Glycoprotein A repetitions predominant (GARP) positively regulates transforming growth factor (TGF) β3 and is essential for mouse palatogenesis.
These results demonstrate the unexpected presence of GARP on Hepatic stellate cells and its significance in regard to the ability of Hepatic stellate cells to activate latent TGF-beta1 and thereby inhibit T cells.

We conclude that a missense mutation in VPS54, an essential component of the Golgi-associated retrograde protein complex, not only prevents the formation of an acrosome but also initiates a cascade of metabolic abnormalities and a stress reaction.

These findings suggest a role for GARP in natural and induced Treg development through activation of bound latent TGF-beta and signaling, which negatively regulates GARP expression on Tregs.

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.
