Spinophilin Antibody recognizes endogenous levels of total spinophilin protein.

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala369 of human spinophilin protein. Antibodies are purified by protein A and peptide affinity chromatography.

Spinophilin is an 815 amino acid protein composed of a PDZ domain, 2 actin-binding domains, a receptor- and PP1-binding domain, three coiled-coiled domains, a potential leucine/isoleucine zipper motif, and three potential SH3 domains (1). Spinophilin interacts with a large number of proteins including ion channel components and G protein-coupled receptors (GPCRs). Spinophilin also interacts with actin filaments; phosphorylation of spinophilin at Ser94 and Ser177 disrupts this interaction (2). Spinophilin has been shown to affect GPCR function through two different mechanisms: spinophilin acts as a functional inhibitor of α-2 adrenergic receptor-mediated arrestin signaling by competing with GRK2 binding to the adrenergic receptor (3) and spinophilin facilitates μ-opioid receptor desensitization by promoting receptor endocytosis (4).
