SNRPC (Small Nuclear Ribonucleoprotein Polypeptide C, SNRP-C)

Antibodies / Antibodies-Nuclear Proteins

-20°C

Supplied as a liquid in PBS, pH 7.4, 0.02% sodium azide, 50% glycerol.

Recombinant protein corresponding to Pro2-Arg159 of human SNRPC, fused to His-Tag and T7-tag at N-terminal expressed in E. coli.

The C polypeptide is one of the specific protein constituents of the U1 snRNP (small nuclear ribonucleoprotein) particle. See SNRPA. Patients with connective tissue diseases often produce autoantibodies against snRNP particles. By screening human expression libraries with anti-RNP sera, both Yamamoto et al. (1988) and Sillekens et al. (1988) isolated cDNAs encoding SNRPC. Using Northern blot hybridization, Yamamoto et al. (1988) determined that SNRPC is expressed as an approximately 0.8-kb mRNA. Antibodies against SNRPC stained the nuclei of HeLa cells in a speckled pattern. Sillekens et al. (1988) reported that the predicted 159aa SNRPC protein has an apparent molecular mass of 22kD by SDS-PAGE.
