A Novel Interaction between Perlecan Protein Core and Progranulin

A Novel Interaction between Protein Kinase

Novel progranulin variants do not disrupt progranulin secretion and cleavage.

A subset of frontotemporal dementia cases are neuropathologically defined by tau-negative, TAR DNA-binding protein-43, and ubiquitin-positive inclusions in the brain and are associated with mutations in the progranulin gene (GRN). Deep sequencing of families exhibiting late-onset dementia revealed several novel variants in GRN. Because of the small size of these families and limited availabilit...

A role for the perlecan protein core in the activation of the keratinocyte growth factor receptor.

Perlecan, a widespread heparan sulphate (HS) proteoglycan, is directly involved in the storing of angiogenic growth factors, mostly members of the fibroblast growth factor (FGF) gene family. We have previously shown that antisense targeting of the perlecan gene causes a reduced growth and responsiveness to FGF7 [also known as keratinocyte growth factor (KGF)] in human cancer cells, and that the...

Physical and functional interaction between a nucleolar protein nucleophosmin/B23 and adenovirus basic core proteins.

We identified nucleophosmin/B23 as a component of template-activating factor-III that stimulates the DNA replication from the adenovirus DNA complexed with viral basic core proteins. Here, we have studied the functional interaction of B23 with viral core proteins. We found that B23 interacts with viral basic core proteins, core protein V and precursor of core protein VII (pre-VII), in infected ...

Association Between Progranulin and Gaucher Disease

BACKGROUND Gaucher disease (GD) is a genetic disease caused by mutations in the GBA1 gene which result in reduced enzymatic activity of β-glucocerebrosidase (GCase). This study identified the progranulin (PGRN) gene (GRN) as another gene associated with GD. METHODS Serum levels of PGRN were measured from 115 GD patients and 99 healthy controls, whole GRN gene from 40 GD patients was sequenced...
