**Background of AKAP7 Recombinant Protein**
A-kinase anchoring protein 7 (AKAP7), also known as AKAP18. is a member of the AKAP family that plays a critical role in compartmentalizing cyclic AMP (cAMP)-dependent protein kinase A (PKA) signaling within cells. AKAP7 anchors PKA to specific subcellular locations, enabling spatially restricted phosphorylation of downstream targets, which is essential for regulating diverse physiological processes, including cardiac contraction, ion channel modulation, and cellular differentiation.
The AKAP7 gene undergoes alternative splicing, producing multiple isoforms (e.g., α, β, γ, δ) that vary in size, localization, and function. For instance, AKAP7γ is predominantly expressed in the heart and skeletal muscle, where it interacts with phospholamban to regulate calcium handling in cardiomyocytes. AKAP7α, in contrast, localizes to the nucleus and may influence gene transcription.
Recombinant AKAP7 proteins are engineered in vitro to study its structure-function relationships, isoform-specific roles, and interactions with PKA and other signaling partners. These proteins are typically produced using bacterial or mammalian expression systems, often fused with tags (e.g., His, GST) for purification and detection. Researchers utilize AKAP7 recombinant proteins to dissect cAMP/PKA signaling mechanisms, develop therapeutic strategies targeting AKAP-mediated pathways (e.g., heart failure, arrhythmias), or screen for small-molecule disruptors of AKAP-PKA interactions.
Notably, dysregulation of AKAP7 has been implicated in cardiovascular diseases and neurological disorders, underscoring its biomedical relevance. The availability of recombinant AKAP7 facilitates high-resolution structural studies (e.g., X-ray crystallography) and functional assays, advancing our understanding of localized cAMP signaling and its therapeutic potential.
