Disease relevance of Grk1

  • Furthermore, eNOS activation was not dependent on tyrosine phosphorylation, and pretreatment of endothelial cells with pertussis toxin as well as overexpression of a dominant negative G-protein-coupled receptor kinase construct that sequesters betagamma subunits inhibited Akt phosphorylation and NO synthesis [1].
  • We have found that significantly low levels of expression of rhodopsin kinase (RK) and alphaA-crystallin may be involved in the pathogenesis of retinal degeneration in the RCS rat (Invest Ophthalmol Vis Sci. 1999,40:2788-2794) [2].
  • Rhodopsin kinase (RK), an enzyme probably unique to the mammalian eye, is reported here to resemble the retinal S-Ag in its capacity to induce uveitis in experimental animals [3].

Analytical, diagnostic and therapeutic context of Grk1

  • Analysis by SDS-PAGE of ROS proteins and by western blot using antibodies against opsin, rhodopsin kinase (RK), recoverin, or arrestin demonstrated that a 20-kDa protein and RK were selectively less abundant in RCS than in control rats [22].
  • Immunohistochemistry (IHC) and Western blot analysis were carried out using antibodies against RK and G(talpha) (alpha subunit of G(t)) in the STZ-induced diabetic retina and the control retina [11].
