• Application Notes: IHC: 1:50-1:200; Peptide ELISA: 1:20,000-1:40,000
• Immunogen: A synthesized peptide derived from human PKA R2 around the phosphorylation site of Ser99.
• Conjugation: Unconjugated
• Fragment: Fab fragment
• Post Translational Modifications: Phosphorylated by the activated catalytic chain.
• Subunit Structure: The inactive form of the enzyme is composed of two regulatory chains and two catalytic chains. Activation by cAMP produces two active catalytic monomers and a regulatory dimer that binds four cAMP molecules. Interacts with AKAP4 and CBFA2T3. Interacts with the phosphorylated form of PJA2. Interacts with MYRIP. This interaction may link PKA to components of the exocytosis machinery, thus facilitating exocytosis, including insulin release (By similarity). Forms a complex composed of PRKAR2A, GSK3B and GSKIP through GSKIP interaction; facilitates PKA-induced phosphorylation and regulates GSK3B activity. Interacts with ADCY8; inhibits adenylate cyclase activity through PKA phosphorylation.
• Similarity: Belongs to the cAMP-dependent kinase regulatory chain family.
• Subcellular Location: Cytoplasm. Cell membrane.; Note: Colocalizes with PJA2 in the cytoplasm and the cell membrane.
• Preparation and Storage: Store at -20 degree C. Stable for 12 months from date of receipt.

Immunohistochemistry (IHC)

(At 1/100 staining Human kidney cancer by IHC-P. The sample was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The sample was then blocked and incubated with the primary antibody at 4 degree C overnight. An HRP conjugated anti-Rabbit antibody was used as the secondary antibody.)

NCBI Description

cAMP is a signaling molecule important for a variety of cellular functions. cAMP exerts its effects by activating the cAMP-dependent protein kinase, which transduces the signal through phosphorylation of different target proteins. The inactive kinase holoenzyme is a tetramer composed of two regulatory and two catalytic subunits. cAMP causes the dissociation of the inactive holoenzyme into a dimer of regulatory subunits bound to four cAMP and two free monomeric catalytic subunits. Four different regulatory subunits and three catalytic subunits have been identified in humans. The protein encoded by this gene is one of the regulatory subunits. This subunit can be phosphorylated by the activated catalytic subunit. It may interact with various A-kinase anchoring proteins and determine the subcellular localization of cAMP-dependent protein kinase. This subunit has been shown to regulate protein transport from endosomes to the Golgi apparatus and further to the endoplasmic reticulum (ER). [provided by RefSeq, Jul 2008]
