  • Function

    Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. Transducin is an amplifier and one of the transducers of a visual impulse that performs the coupling between rhodopsin and cGMP-phosphodiesterase.
  • Tissue specificity

    Rod. Predominantly expressed in the retina followed by the ciliary body, iris and retinal pigment epithelium.
  • Involvement in disease

    Night blindness, congenital stationary, autosomal dominant 3
    Night blindness, congenital stationary, 1C
  • Sequence similarities

    Belongs to the G-alpha family. G(i/o/t/z) subfamily.
  • Developmental stage

    Expressed at approximately postnatal day 7.
