National Institute on Drug Abuse (NIDA)


This addendum is to program announcement (PA) PA-02-060, which was 
released in the NIH Guide for Grants and Contracts on February 11, 2002 
This PA is intended to support research on the structure of membrane 
proteins at atomic resolution.  This addendum adds the National 
Institute on Drug Abuse (NIDA) as a participating institute in this 
program announcement.

The NIDA is interested in furthering the understanding of membrane 
protein receptors and transporters, their structure, and their 
interaction with ligands relevant to drug abuse research.  These 
proteins include:  the cannabinoid CB1 and CB2 receptors, the vanilloid 
receptor, the orphanin receptor, the mu, delta, and kappa opioid 
receptors, the neuronal nicotinic receptor subtypes, the NMDA receptor 
complex, the metabotropic glutamate receptors I-III, the GABA-A 
receptor, and the dopamine, serotonin, and norepinephrine transporters 
and any other neuropeptide receptors that are affected by drugs of abuse. 

Applicants are encouraged to develop techniques to express, solubilize, 
purify, and stabilize these receptors and transporters, and to obtain 
structural information (diffraction, NMR, microscopy) on single 
particles or crystals, as described in the PA.

The following are NIDA contacts:
