The family of small heat shock proteins (sHsp) is composed of 10 members in mammals, four of which are found mutated in diseases associated with the accumulation of protein aggregates. Though many sHsp have demonstrated molecular chaperone activity in vitro in cell-free conditions, their activity in vivo in the normal cellular context remains unclear. In(More)
We recently mapped Idd4 to a 5.2 cM interval on chromosome 11 with two subloci, Idd4.1 and Idd4.2, in nonobese diabetic (NOD) mice. Based on the localization of platelet-activating factor acetylhydrolase Ib1 (PAF-AHIb1) and the decreased activity of PAF-AH in type 1 diabetes (T1D) patients, we hypothesized that PAF-AHIb1 in Idd4.1 is a candidate gene.

Investigation of restriction enzyme families observed in Bam HI and Eco RI digest of guinea pig DNA has led to the demonstration of a 4.0 kb cryptic satellite called MRICp which has 6300 copies and comprises 1% of the total genome. MRICp has been shown to encompass the Eco RI 4.0 kb family, the Bam HI 3.4 kb family and the Bam HI 3.7 kb family. The 1.5 kb(More)
