The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/100 - 1/500. Detects a band of approximately 46 kDa (predicted molecular weight: 46 kDa).
FunctionRegulatory 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.
Tissue specificityFour 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.
Sequence similaritiesBelongs to the cAMP-dependent kinase regulatory chain family. Contains 2 cyclic nucleotide-binding domains.
Post-translational modificationsPhosphorylated by the activated catalytic chain.
Cellular localizationCytoplasm. Cell membrane. Co-localizes with PJA2 in the cytoplasm and at the cell membrane.
