General description

Dopamine- and cAMP-regulated neuronal phosphoprotein (DARP-32) is a cytoplasmic member of the protein phosphatase inhibitor 1 family. DARP-32 is a multifunctional protein kinase and protein phosphatase regulator, depending on the site of its activation. It possesses at least four sites that can be phosphorylated. Phosphorylation by PKA at Thr34 stimulates DARP-32 to act as a protein-phosphatase-1 (PP-1) inhibitor. However, phosphorylation at Thr75 will inhibit Thr34 phosphorylation. This selective, bidirectional regulation allows DARPP-32 to have a wide range of influence on downstream physiological effectors such as: ion pumps, neurotransmitter receptors, voltage-gate ion channels, and transcriptional factors. Studies suggest that it may also have a role in the Circadian System photic pathway. Overexpression of DARPP-32 has been linked with antiapoptotic mechanisms of cancer cells and has been observed in breast, colon, esophagus, gastric, and prostate cancer tissues.

Specificity

This antibody recognizes DARPP-32 near the N-terminus.

Immunogen

Manganese (Mn) is an essential trace element, but excess exposure leads to accumulation in biological tissues, including the brain. Chronically high Mn levels in the brain are neurotoxic and can result in a progressive, irreversible neurological disorder known as manganism.
