Structural basis for the interaction of unstructured neuron specific substrates neuromodulin and neurogranin with Calmodulin.

Sci Rep 2013 ;3:1392

Department of Biological Sciences, National University of Singapore, Singapore.

Neuromodulin (Nm) and neurogranin (Ng) are neuron-specific substrates of protein kinase C (PKC). Their interactions with Calmodulin (CaM) are crucial for learning and memory formation in neurons. Here, we report the structure of IQ peptides (24aa) of Nm/Ng complexed with CaM and their functional studies with full-length proteins. Read More

Mechano Growth Factor E peptide (MGF-E), derived from an isoform of IGF-1, activates human muscle progenitor cells and induces an increase in their fusion potential at different ages.

Mech Ageing Dev 2011 Apr 25;132(4):154-62. Epub 2011 Feb 25.

Loss of muscle mass and strength is a major problem during aging and the expression of Mechano Growth Factor (MGF), a member of the IGF-1 (insulin-like Growth Factor 1) super family, has been shown to be both exercise and age dependent. MGF, also called IGF-1Ec, has a unique E domain with a 49bp insert in humans (52bp in rodents; IGF-1Eb), which results in a reading frame shift during the IGF-1 gene splicing to produce a distinct mature isoform. We have studied the effects of the MGF-24aa-E peptide on proliferation and differentiation of primary human muscle cell cultures isolated from healthy subjects of different ages. Read More

Conantokin-P, an unusual conantokin with a long disulfide loop.

Toxicon 2008 Aug 3;52(2):203-13. Epub 2008 Jun 3.

Department of Biology, University of Utah, Salt Lake City, UT 84112, USA.

The conantokins are a family of Conus venom peptides (17-27AA) that are N-methyl-d-aspartate (NMDA) receptor antagonists. Conantokins lack disulfide bridges (six out of seven previously characterized peptides are linear), but contain multiple residues of gamma-carboxyglutamate. These post-translationally modified amino acids confer the largely helical structure of conantokins by coordinating divalent metal ions. Read More

Subpopulation of dogs with severe brain parenchymal beta amyloidosis distinguished with cluster analysis.

Brain Res 1996 Jul;728(1):20-6

Department of Pathological Neurobiology, New York State Institute for Basic Research in Developmental Disabilities, Staten Island 10314, USA.

A study of the brains of 30 dogs, mongrels from 6.5 to 26.5 years of age, revealed that all dogs older than 13 years of age develop amyloid-beta-positive plaques. Read More
