General description

Regulator of G-protein signaling 13 is a protein encoded by the RGS13 gene in humans. It is a member of R4 subfamily of RGS (Regualtors of G Protein Signaling) proteins and is a GTPase-activating protein for Gα(i) and Gα(o). RGS13 helps in suppressing IgE-antigen-induced MC degranulation and anaphylaxis. It is the smallest member of the RGS family and is abundantly found in human tonsil, followed by thymus, lung, lymph node and spleen.


Immunogen Sequence: GI # 4506511, sequence 42-99

Recombinant regulator of G-protein signalling 13


Anti-RGS13 antibody produced in chicken is suitable for western blotting analysis at a dilution of 1:500, for tissue or cell staining at a dilution of 1:200.

Physical form

Solution in phosphate buffered saline containing 0.02% sodium azide.

Biochem/physiol Actions

Regulator of G-protein signaling 13 (RGS13) expression is induced by immune receptor and chemokine receptor stimulation. It may help in regulating Gα(i)-, Gα(q)- and Gα(s)-coupled signaling cascades. RGS13 inhibits the assembly of immune receptor-induced signalosomes in mast cells and its abnormal expression or function may contribute to disorders of amplified mast cell activity (such as idiopathic anaphylaxis). RGS13, along with RGS1, acts together to regulate chemokine receptor signaling in human germinal center B lymphocytes and contribute significantly to the rapid desensitization of the signaling pathway. It restricts certain GPCR-mediated biological responses of human mast cells. RGS13 inhibits cyclic AMP-dependent protein kinase (PKA)-induced gene expression through interactions with the transcription factor cAMP-response element-binding (CREB) protein.
