Activation of the ERK/MAPK pathway by an isoform of rap1GAP associated with G alpha(i)

abstract：:Visual transduction in vertebrate photoreceptors is thought to involve a diffusible internal transmitter which links photon absorption in disk membranes to the conductance decrease in the plasma membrane of the outer segment. The desensitisation of the photoresponse which occurs during and after illumination may also ...
