Disease relevance of Adaptation, Ocular

  • Sensitivity-modulating protein (S-modulin) is a Ca(2+)-binding protein involved in light adaptation in frog rods; it regulates both the light sensitivity of PDE and the lifetime of activated PDE by controlling rhodopsin phosphorylation in a Ca(2+)-dependent manner [1].
  • Since dopamine is especially involved in light adaptation from darkness, the residual retina could act in triggering the turning behavior of Proteus in response to lightening [2].
  • Furthermore, Na+ channel modulation is implicated in the control of input-output relationships in several types of neuron and seems to be involved in phenomena as varied as cocaine withdrawal, hyperalgesia and light adaptation [3].

High impact information on Adaptation, Ocular

  • The intensity dependence of the photoresponse in rods lacking arrestin further suggests that, although arrestin is required for normal signal termination, it does not participate directly in light adaptation [5].
  • We now show that under physiological conditions light adaptation is severely reduced in inaC, suggesting that eye-specific PKC, itself activated by a rise in cytosolic calcium and diacylglycerol, is required for adaptation [6].
  • On the basis of these studies, Ca2+ is suggested to play a central role in photorecovery and light adaptation, not only by regulating guanylate cyclase, possibly through recoverin, but also by modulating the cGMP-gated channel through calmodulin interaction with the 240K protein [7].
  • This is believed to be one of the mechanisms of light-adaptation produced by activation of guanylate cyclase [8].
  • Similarly, 'light adaptation' involves decreased coupling of photoactivated rhodopsin to cGMP phosphodiesterase activation [9].

Gene context of Adaptation, Ocular

  • These findings indicate that light-dependent trafficking of arrestin is regulated by direct interaction with PIs and is required for light adaptation [24].
  • Localization of heme oxygenase in rat retina: effect of light adaptation [25].
  • A key component in dark/light adaptation is phosducin, a phosphorylatable protein that modulates the amount of transducin heterotrimer (Gt alpha beta gamma) available through sequestration of the beta gamma subunits (Gt beta gamma) [26].
  • In this system, we investigate the hitherto unknown physiological roles of calmodulin (CaM) in light adaptation and in regulation of the inward current that is brought about by depletion of cellular Ca2+ stores [15].
  • The results indicate that light adaptation is primarily mediated downstream of PLC and independently of PKC by Ca(2+)-dependent inhibition of TRP channels [27].
