α,β-Methyleneadenosine 5′-triphosphate lithium salt has been used:
  • as P2-purinoreceptor agonist (P2X), to analyse its effects on membrane conductance in the astrocytes of caudal nucleus
  • as a P2X receptor agonist, to increase the calcium current in the neurons in satellite cells
  • to determine the functional sensitivities of purinergic agonists on P2Y receptors in rat and to determine its effect on developing outer sulcus cells

To characterize [3H] alpha, beta-methylene adenosine 5'-triphosphate ([3H] alpha, beta-MeATP, a radioligand for P2x-purinoceptors) binding sites in the washed homogenates and membrane preparations of human urinary bladder and, using autoradiography, to localize [3H] alpha, beta-MeATP binding sites in human bladder.

1. We have previously found that the P2x-purinoceptor agonist, alpha, beta-methylene adenosine 5'-triphosphate (alpha, beta-methylene ATP), depolarizes the rat cervical vagus nerve, measured with a 'grease-gap' extracellular recording technique. This effect was attenuated by the P2 purinoceptor antagonist, suramin. In

It is suggested that the P2-purinoceptor may be separated into two subtypes largely on the basis of the rank order of agonist potency of structural analogues of ATP and also on the activity of antagonists at the P2-purinoceptor: Subtype 1

DNA polymerase delta (Pol δ) is responsible for the elongation and maturation of Okazaki fragments in eukaryotic cells. Proliferating cell nuclear antigen (PCNA) recruits Pol δ to the DNA and serves as a processivity factor. Here, we show that PCNA
