| Type: | Family | Name: | Phosducin |
| Description: | The outer and inner segments of vertebrate rod photoreceptor cells contain phosducin, a soluble phosphoprotein that complexes with the beta/gamma-subunits of the GTP-bindingprotein, transducin. Light-induced changes in cyclic nucleotide levels modulate the phosphorylation of phosducin by protein kinase A []. The protein is thought to participate in the regulation ofvisual phototransduction or in the integration of photo-receptor metabolism. Similar proteins have been isolated from the pineal gland and it is believed that the functionalrole of the protein is the same in both retina and pineal gland []. | Short Name: | Phosducin |
