Synaptojanin is a nerve terminal protein of relative molecular mass 145,000 which appears to participate with dynamin in synaptic vesicle recycling. The central region of synaptojanin defines it as a member of the inositol-5-phosphatase family, which includes the product of the gene that is defective in the oculocerebrorenal syndrome of Lowe.

rbSec1 is a mammalian neuronal protein homologous to the yeast SEC1 gene product which is required for exocytosis. Mutations in Sec1 homologues in the nervous systems of C. elegans and D. melanogaster lead to defective neurotransmitter secretion. Biochemical studies have shown that recombinant rbSec1 binds syntaxin 1 but not SNAP-25 or synaptobrevin/VAMP,(More)
Synaptic vesicle recycling is a specialized form of membrane recycling which takes place in all cells between early endosomes and the plasmalemma. Synaptic vesicles exocytosis is highly regulated and occurs only at presynaptic active zones. In contrast, exocytosis of endosome-derived vesicles of the housekeeping recycling pathway takes place constitutively(More)
Rabphilin 3a is a Rab 3-GTP binding protein concentrated on secretory vesicles of neurons and endocrine cells. There is evidence that rabphilin 3a undergoes cycles of association-dissociation with membranes and that recruitment of rabphilin 3a to secretory vesicles is mediated by Rab 3a, suggesting that rabphilin 3a is a downstream effector of this Rab.

The Veterans Affairs Hypertension Primary Care Longitudinal Cohort (VAHC) was initiated in 2003 as a pilot study designed to link the VA electronic medical record system with individual genetic data. Between June 2003 and December 2004, 1,527 hypertensive participants were recruited. Protected health information (PHI) was extracted from the regional VA data(More)
