TEXT

Cloning and Expression

By EST database searching with the conserved C-terminal sequence of serine kinases and screening of a human ductal pancreatic cDNA library, Sturany et al. (2001) cloned a novel serine/threonine protein kinase, which they called PKD2. The deduced 878-amino acid protein, which has a predicted molecular mass of 97 kD, contains an N-terminal hydrophobic area predicted to be a transmembrane region, 2 cysteine-rich motifs that form zinc finger-like repeats, a pleckstrin homology domain, and a putative kinase domain containing the ATP-binding consensus sequence. An invariant aspartate essential for kinase activity is located within a motif conserved in serine/threonine kinases. The first zinc finger-like domain shares 88% identity to the corresponding domains in PKD/PKC-mu (PRKCM; 605435) and PKC-nu (PRKCN; 607077). Northern blot analysis detected constitutive low expression of a 4-kb transcript; higher levels were observed in pancreas, heart, lung, smooth muscle, and brain, and lower levels kidney and liver. SDS-PAGE revealed a protein with a molecular mass of 105 kD, as did Western blot analysis of endogenous PRKD2 or protein expressed following transfection.


Gene Function

Sturany et al. (2001) demonstrated phorbol ester binding to the duplex zinc finger-like motif of PRKD2 as well as autophosphorylation following phorbol ester stimulation. The addition of phosphatidyl-L-serine caused synergistic stimulation. Phorbol ester-activated PRKD2 migrated more slowly than inactive PRKD2 by SDS-PAGE, suggesting hyperphosphorylation upon activation.


Mapping

The International Radiation Hybrid Mapping Consortium mapped the PRKD2 gene to chromosome 19 (R67403).
