GABARAP
Gamma-aminobutyric acid receptor-associated protein is a protein that in humans is encoded by the GABARAP gene.[5]
Function
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.[6]
Moreover, GABARAP has an important function in autophagosome mediated autophagy, since it is crucial for autophagosome formation and sequestration of cytosolic cargo into double-membrane vesicles, leading to subsequent degradation after fusion with lysosomes.[7] In addition, GABARAP can mediate selective autophagy because it binds to so-called autophagic receptors (e.g. p62, NBr1), which bind and recruit specific cargo.
Interactions
GABARAP has been shown to interact with TFRC,[8] ULK1[9][10] and GABRG2.[5][11][12] A bound structure for GABARAP to GABRG2 consistent with experimental observations has been computationally derived.[13]
