Human Gene AKAP9 (ENST00000356239.8) from GENCODE V44
Description: Homo sapiens A-kinase anchoring protein 9 (AKAP9), transcript variant 2, mRNA. (from RefSeq NM_005751) RefSeq Summary (NM_005751): 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. This gene encodes a member of the AKAP family. Alternate splicing of this gene results in at least two isoforms that localize to the centrosome and the Golgi apparatus, and interact with numerous signaling proteins from multiple signal transduction pathways. These signaling proteins include type II protein kinase A, serine/threonine kinase protein kinase N, protein phosphatase 1, protein phosphatase 2a, protein kinase C-epsilon and phosphodiesterase 4D3.

ID:AKAP9_HUMAN DESCRIPTION: RecName: Full=A-kinase anchor protein 9; Short=AKAP-9; AltName: Full=A-kinase anchor protein 350 kDa; Short=AKAP 350; Short=hgAKAP 350; AltName: Full=A-kinase anchor protein 450 kDa; Short=AKAP 450; AltName: Full=AKAP 120-like protein; AltName: Full=Centrosome- and Golgi-localized PKN-associated protein; Short=CG-NAP; AltName: Full=Protein hyperion; AltName: Full=Protein kinase A-anchoring protein 9; Short=PRKA9; AltName: Full=Protein yotiao; FUNCTION: Binds to type II regulatory subunits of protein kinase A. Scaffolding protein that assembles several protein kinases and phosphatases on the centrosome and Golgi apparatus. May be required to maintain the integrity of the Golgi apparatus. Isoform 4 is associated with the N-methyl-D-aspartate receptor and is specifically found in the neuromuscular junction (NMJ) as well as in neuronal synapses, suggesting a role in the organization of postsynaptic specializations. SUBUNIT: Interacts with the regulatory region of protein kinase N (PKN), protein phosphatase 2A (PP2A), protein phosphatase 1 (PP1) and the immature non-phosphorylated form of PKC epsilon. Interacts with CIP4 and FNBP1. Interacts with chloride intracellular channel proteins CLIC1, CLIC4 and CLIC5. CSNK1D binding promotes its centrosomal subcellular location. SUBCELLULAR LOCATION: Cytoplasm. Cytoplasm, cytoskeleton, centrosome. Golgi apparatus. Note=Cytoplasmic in parietal cells. TISSUE SPECIFICITY: Widely expressed. Isoform 4 is highly expressed in skeletal muscle and in pancreas. DOMAIN: RII-binding site, predicted to form an amphipathic helix, could participate in protein-protein interactions with a complementary surface on the R-subunit dimer. PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. DISEASE: Defects in AKAP9 are the cause of long QT syndrome type 11 (LQT11) [MIM:611820]. Long QT syndromes are heart disorders characterized by a prolonged QT interval on the ECG and polymorphic ventricular arrhythmias. They cause syncope and sudden death in response to excercise or emotional stress. They can present with a sentinel event of sudden cardiac death in infancy.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
