Roquin-1 shares 46% identity with Roquin-2 and both serve the same function and belong to the Zinc finger family of RNA binding proteins. Roquin-1/2 are cytoplasmic RNA suppression proteins that specifically bind selective RNAs and promote the deadenylation of mature mRNAs and their degradation. Roquin-1/2s targets include HMGXB3, ICOS, IER3, NFKBID, NFKBIZ, PPP1R10, TNF and in many more critical RNAs. In particular, because of their impact on ICSO and gamma interferon and T helper cell activation, Roquin-1/2 are being examined as mediators of the systemic inflammation response and controllers of adaptive and innate immune responses in autoimmune disease. Roquin 1/2 are widely expressed and localized in the cytoplasm and/or P bodies and cytosolic stress granules when under cellular stress.

This antibody specifically detects both Roquin-1 & Roquin-2 (Vogel, K.U., et al. (2013). Immunity. 38:655-668).

Recombinant protein corresponding to human Roquin-1/2.

This Anti-Roquin-1/2, clone 3F12 Antibody is validated for use in Western Blotting and Immunoprecipitation for the detection of Roquin-1/2.

Western Blotting Analysis: A representative lot detected Roquin-1/2 in both Roquin-1 & Roquin-2 in normal MEFs, only Roquin-2 and Roquin-1 deficient MEFs, and neither protein in Roquin-1/2 deficient MEFs. This antibody also detected Roquin-1 and Roquin-2 in Mouse Spleen, Lymph Node, Thymus, Brain & Lung tissue, CD4+ T cells and Thymocyte lysates (Vogel, K.U., et al. (2013). Immunity. 38:655-668).
Immunoprecipitation Analysis: A representative lot immunoprecipitated Roquin-1/2 in MEF cell lysate (Vogel, K.U., et al. (2013). Immunity. 38:655-668).
