Function

[GBRAP_HUMAN] May play a role in intracellular transport of GABA(A) receptors and its interaction with the cytoskeleton. Involved in apoptosis. Involved in autophagy (By similarity).^[1] [CALR_HUMAN] Calcium-binding chaperone that promotes folding, oligomeric assembly and quality control in the endoplasmic reticulum (ER) via the calreticulin/calnexin cycle. This lectin interacts transiently with almost all of the monoglucosylated glycoproteins that are synthesized in the ER. Interacts with the DNA-binding domain of NR3C1 and mediates its nuclear export. Involved in maternal gene expression regulation. May participate in oocyte maturation via the regulation of calcium homeostasis (By similarity).^[2] ^[3]

Publication Abstract from PubMed

The 4-aminobutyrate type A receptor-associated protein (GABARAP) is a versatile adaptor protein that plays an important role in intracellular vesicle trafficking, particularly in neuronal cells. We have investigated the structural determinants underlying the interaction of GABARAP with calreticulin using spectroscopic and crystallographic techniques. Specifically, we present the crystal structure of GABARAP in complex with its major binding epitope on the chaperone. Molecular modeling of a complex containing full-length calreticulin suggests a novel mode of substrate interaction, which may have functional implications for the calreticulin/calnexin family in general.
