Gamma-aminobutyric acid receptor-associated protein is a protein that in humans is encoded by the GABARAP gene.[1]

Gamma-aminobutyric acid A receptors [GABA(A) receptors] are ligand-gated chloride channels that mediate inhibitory neurotransmission. This gene encodes GABA(A) receptor-associated protein, which is highly positively charged in its N-terminus and shares sequence similarity with light chain-3 of microtubule-associated proteins 1A and 1B. This protein clusters neurotransmitter receptors by mediating interaction with the cytoskeleton.[2]

A study has screened 2000 participants representing more than 600 families of smokers and examined different genes showing linkage to nicotine addiction. Some of these showing linkage are the GABA-B receptor subunit 2 (GABAB2) gene on chromosome 9, and the GABA-A receptor-associated protein (GABARAP) gene on chromosome 17.[3]

Interactions[edit]

GABARAP has been shown to interact with TFRC,[4] ULK1[5][6] and GABRG2.[1][7][8]
