Protein kinase A regulates chloride conductance in endocytic vesicles from proximal tubule.

abstract：:The genes for the T-cell receptor, like the immunoglobulin genes, are rearranged as DNA. The mechanism of this rearrangement is not clear; unequal crossover between chromosomes and the looping-out and excision of the excess DNA have both been suggested. We isolated small polydisperse circular (spc) DNAs from mouse thy...
