Reactivity Human, Mouse, Rat
Host Rabbit
Clonality Monoclonal
Clone Names E151
Calculated MW 45518 Da
Gene ID 5576
Other Names cAMP-dependent protein kinase type II-alpha regulatory subunit, PRKAR2A, PKR2, PRKAR2
Target/Specificity A synthetic phospho-peptide corresponding to residues surrounding Ser99 of human PKA RII was used as immunogen. The antibody only detects PKA RII phosphorylated on Serine 99.

StorageMaintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.
PrecautionsPKA, RII Antibody Phospho (pS99) is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Synonyms PKR2, PRKAR2
Function Regulatory subunit of the cAMP-dependent protein kinases involved in cAMP signaling in cells. Type II regulatory chains mediate membrane association by binding to anchoring proteins, including the MAP2 kinase.
Cellular Location Cytoplasm. Cell membrane. Note=Colocalizes with PJA2 in the cytoplasm and the cell membrane
Tissue Location Four types of regulatory chains are found: I- alpha, I-beta, II-alpha, and II-beta. Their expression varies among tissues and is in some cases constitutive and in others inducible

PKA (or cAPK) is a cyclic AMP-dependent protein kinase. When activated by the second messenger cAMP, PKA mediates diverse cellular mechanisms, including proliferation, ion transport, regulation of metabolism, and gene transcription (1,2). PKA is comprised of two dimers of two subunits, R (regulatory) and C (catalytic). Two families of R subunits (RI and RII) have been identified, each possessing distinct cAMP binding properties and resulting in different phosphorylation states (2,3).
