background:
The A Kinase Anchor proteins (AKAPs) are a group of structurally diverse proteins, which have the common function of binding to the regulatory subunit of protein kinase A (PKA) and confining the holoenzyme to discrete locations within the cell. AKAP6 is a member of the AKAP family. It is highly expressed in various brain regions and cardiac and skeletal muscle. It is specifically localized to the sarcoplasmic reticulum and nuclear membrane, and is involved in anchoring PKA to the nuclear membrane or sarcoplasmic reticulum.
Function:
Binds to type II regulatory subunits of protein kinase A and anchors/targets them to the nuclear membrane or sarcoplasmic reticulum. May act as an adapter for assembling multiprotein complexes.
Subunit:
Interacts with RII subunit of PKA, phosphatase 2B (calcineurin) and AKAP79.
Subcellular Location:
Sarcoplasmic reticulum. Nucleus membrane. Note=In heart muscle. Participation of multiple targeting signals allow correct intracellular targeting. These may be repeated motifs rich in basic and hydrophobic amino acids, palmitoylated/myristoylated motifs or alternatively splice targeting sequences.
Tissue Specificity:
Highly expressed in cardiac and skeletal muscle, followed by brain.
Similarity:
Contains 2 spectrin repeats.
Database links:
UniProtKB/Swiss-Prot: Q13023.3
