Anti-Iporin RUSC2 Antibody

RUSC2, also known as Iporin, shares with the related protein RUSC1 a common domain structure of RUN, leucine zipper and SH3 domain in addition to over 30% amino acid identity. RUSC2 is a rab1-interacting protein that also interacts with GM130, another rab1-interacting protein. RUSC2 interacts with specific rab1 isoforms with different rab-binding specificity. It has been suggested that RUSC2 may function as a link between the targeting of ER derived vesicles triggered by the rab1 GTPase and a signaling pathway composed of proteins containing SH3 and/or poly-proline regions.

At least three isoforms are known to exist; this antibody will only detect the longest isoform. This antibody is predicted to not cross-react with RUSC1.

RUSC2 antibody was raised against a 15 amino acid synthetic peptide from near the carboxy terminus of human RUSC2. The immunogen is located within amino acids 1410 - 1460 of RUSC2.

RUSC2 antibody can be stored at 4°C for three months and -20°C, stable for up to one year. Avoid repeated freeze-thaw cycles. Antibodies should not be exposed to prolonged high temperatures.
