Heat shock protein 20 (HSP20) is a novel substrate for protein kinase D1 (PKD1)
Heat shock protein 20 (HSP20) has cardioprotective qualities, which are triggered by PKA phosphorylation. PKD1 is also a binding partner for HSP20, and this prompted us to investigate whether the chaperone was a substrate for PKD1. We delineate the PKD1 binding sites on HSP20 and show for the first time HSP20 is a substrate for PKD1. Phosphorylation of HSP20 by PKD1 is diminished by pharmacolog...
متن کاملCritical role for heat shock protein 20 (HSP20) in migration of malarial sporozoites.
Plasmodium sporozoites, single cell eukaryotic pathogens, use their own actin/myosin-based motor machinery for life cycle progression, which includes forward locomotion, penetration of cellular barriers, and invasion of target cells. To display fast gliding motility, the parasite uses a high turnover of actin polymerization and adhesion sites. Paradoxically, only a few classic actin regulatory ...
متن کاملMolecular cloning and expression analysis of heat shock protein 20 (HSP20) from the pearl oyster Pinctada martensii.
Small heat shock proteins (HSPs) are molecular chaperones with ATP-independent properties. They are involved in a variety of physiological and stress processes. In this study, the full-length HSP 20 (HSP20) from Pinctada martensii, designated as PmHSP20, was obtained from hemocytes using rapid amplification of cDNA ends technology. The PmHSP20 cDNA was 952 bp in length, containing an open readi...
متن کاملTransduction of phosphorylated heat shock-related protein 20, HSP20, prevents vasospasm of human umbilical artery smooth muscle.
Activation of cyclic nucleotide-dependent signaling pathways inhibits agonist-induced contraction of most vascular smooth muscles except human umbilical artery smooth muscle (HUASM). This impaired vasorelaxation may contribute to complications associated with preeclampsia, intrauterine growth restriction, and preterm delivery. Cyclic nucleotide-dependent signaling pathways converge at the phosp...
متن کاملLocalization, macromolecular associations, and function of the small heat shock-related protein HSP20 in rat heart.
BACKGROUND The small heat shock proteins HSP20, HSP25, alphaB-crystallin, and myotonic dystrophy kinase binding protein (MKBP) may regulate dynamic changes in the cytoskeleton. For example, the phosphorylation of HSP20 has been associated with relaxation of vascular smooth muscle. This study examined the function of HSP20 in heart muscle. METHODS AND RESULTS Western blotting identified immuno...
