General description
Calmodulin regulator protein PCP4 (UniProt: P48539; also known as Brain-specific polypeptide PEP-19, Purkinje cell protein 4) is encoded by the PCP4 (also known as PEP19) gene (Gene ID: 5121) in human. Calmodulin (CaM) plays a key role in calcium signaling events and its regulation is an important sically dicomponent of cellular homeostasis. PCP4 is a small IQ motif-containing (aa 39-62), intrinsically disordered protein that functions as a modulator of calcium-binding by CaM. Its acidic region (aa 28-40) is reported to be essential for both modulating calcium-binding to CaM and sensitizing cells to ATP-induced calcium-release. It binds to both calcium-free and calcium-bound forms of CaM, however, its affinity for calcium-bound form is about 50-fold greater. PCP4 is also shown to regulate arrhythmogenicity through a cell-autonomous mechanism within the Purkinje fiber network. It regulates cardiac rhythmicity through modulation of autonomic tone. PEP4 null mice exhibit a dramatic reduction in long term plasticity at synapses between granule cell parallel fibers and Purkinje cells. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Biochem/physiol Actions
Clone 1C4-H2 is a ZooMAb® Rabbit recombinant monoclonal antibody that specifically detects Calmodulin regulator protein PCP4. It targets an epitope within 22 amino acids from the C-terminal region.
Physical form
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.
Preparation Note
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.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
