Rat brain capillary endothelial (B10) cells express an unidentified nucleotide receptor linked to adenylyl cyclase inhibition. We show that this receptor in B10 cells is identical in sequence to the P2Y(12) ADP receptor ( ... More

Water borne cercaria(ae) of the trematode genus Schistosoma rapidly penetrate host skin. A single serine protease activity, cercarial elastase, is deposited in advance of the invading parasite by holocytosis of vesicles from ten large acetabular gland cells. Cercarial elastase activity is a composite of multiple isoforms. Genes coding for the ... More
RasGRP4, a new mast cell-restricted Ras guanine nucleotide-releasing protein with calcium- and diacylglycerol-binding motifs. Identification of defective variants of this signaling protein in asthma, mastocytosis, and mast cell leukemia patients and demonstration of the importance of RasGRP4 in mast cell development and function.

'A cDNA was isolated from interleukin 3-developed, mouse bone marrow-derived mast cells (MCs) that contained an insert (designated mRasGRP4) that had not been identified in any species at the gene, mRNA, or protein level. By using a homology-based cloning approach, the approximately 2.6-kb hRasGRP4 transcript was also isolated from the ... More
Novel Cav2.1 splice variants isolated from Purkinje cells do not generate P-type Ca2+ current.
'The alpha(1)2.1 (alpha(1A)) subunits of P-type and Q-type Ca(2+) channels are encoded by a single gene, Cacna1a. Although these channels differ in the inactivation kinetics and sensitivity to omega-agatoxin IVA, the mechanism underlying these differences remains to be clarified. Alternative splicings of the Cacna1a transcript have been postulated to contribute ... More
