Journal of Stem Cell Research & Therapeutics Review Article Open Access Role of GPCRS towards cell: an explanation of g-protein coupled receptor structure Abstract Volume 2 Issue 3 - 2017 G- protein coupled receptors are the heptahelical, serpentine receptor and are Nidhi Sharma,1 Anil Kumar Sahdev,2 Vinit Raj2 multifunctional receptors having modulatory activity of a wide variety of biological 1Dr. K.

Particularly membrane cholesterol has been reported to have a great role in the functioning of a number of GPCRs. Apart from this it also Correspondence: Vinit Raj, Department of Pharmaceutical have some drawbacks. Mutations that occur are associated with a broad spectrum of Sciences, Babasaheb Bhimrao Ambedkar University, VidyaVihar, diseases of diverse etiology. As a mutations result, there is a change in receptor activity Rae Bareli Road, Lucknow-226025, Email

Changes in the GPCRs functioning can cause diseases Received: January 31, 2017 | Published: March 27, 2017 such as retinitis pigmentosa (rhodopsin mutations), nephrogenic diabetes insipidus (vasopressin receptor mutations), and obesity (melanocortin receptor mutations).
