Description de la cible

Protein phosphatase 1 regulatory subunit 1B (UniProt: Q9UD71; also known as DARPP-32, Dopamine- and cAMP-regulated neuronal phosphoprotein) is encoded by the PPP1R1B (also known as DARPP32) gene (Gene ID: 84152) in human. DARPP-32 is a cytoplasmic protein that is enriched in dopamine-innervated regions of the brain. It serves as a PKA-regulated inhibitor of protein phosphatase-1 that amplifies and/or mediates many actions of PKA at the plasma membrane and in the cytoplasm. It is reported to undergo continuous and tightly regulated cytonuclear shuttling that is controlled by phosphorylation on serine 97, which is necessary for its nuclear export. When phosphorylated on threonine 34 and dephosphorylated on serine 97, it can inhibit PP1 in the nucleus and modulate signaling pathways involved in the regulation of chromatin response. When phosphorylated on threonine 34 it inhibits protein phosphatase 1c in a mixed competitive and uncompetitive manner. A segment in the N-terminal region (aa 8-38) is shown to essential for PP1 inhibition. In this region KKIQF motif that corresponds to the canonical PP1 interacting motif is essential for PP1 inhibition. DARPP-32 activity is regulated by phosphorylation at multiple sites. Cdk5 phosphorylates DARPP-32 on threonine 75, which can lead to PKA inhibition in vitro in a competitive manner. Its phosphorylation on serine 45 and 97 by casein kinase increases the action of PKA on threonine 34. Two isoforms of DARPP-32 have been described that are produced by alternative splicing. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Forme physique

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Reconstitution

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Stockage et stabilité

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
