Anti-Girdin (Ser-1674), Phosphospecific Antibody

Girdin, a member of the CCDC88 (Hook related protein) family, is an actin binding protein involved with cell migration and maintaining cytoskeletal organization. Girdin has conserved domains at the N- and C-terminus that bind microtubules and actin, respectively. It enhances PI3-kinase dependent phosphorylation of proteins, most notably Akt. This same activity can contribute to tumor proliferation, invasion, and metastasis in breast, ovarian, prostate, and pancreatic tissues. Girdin is phosphorylated at three separate locations: Ser-1416, Ser-1674, and Tyr-1764. Ser-1416 is the primary Akt phosphorylation site, while Cyclin-dependent kinases interact with Girdin and phosphorylate Ser-1674. Multiple receptor tyrosine kinases can bind girdin and phosphorylate Tyr-1764.

Our Girdin (Ser-1674) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human, mouse, and rat Girdin (Ser-1674) and is antigen affinity purified. It is great for use in WB.

Phospho-Girdin (Ser-1674) synthetic peptide (coupled to carrier) corresponding to amino acid residues around serine 1674 in human Girdin. This sequence has high homology to rat and mouse Girdin, and has low homology to similar regions in other Girdin family members.

The antibody was cross-adsorbed to unphosphorylated Girdin (Ser-1674) peptide before affinity purification using phospho-Girdin (Ser-1674) peptide. This antibody detects a 250 kDa* protein on SDS-PAGE immunoblots of human A431 cells stimulated with Calyculin A. This reactivity is not observed after lambda phosphatase treatment to dephosphorylate Girdin.
