Note: Can retrotranslocate from the secretory compartments to the cytosol upon cellular stress. Detected in perinuclear foci that may be aggresomes containing misfolded, ubiquitinated proteins. Detected at the mitochondrion membrane upon induction of apoptosis. Under ER stress, a immaturely glycosylated pre-secreted form retrotranslocates from the endoplasmic reticulum (ER)-Golgi network to the cytoplasm to localize in the mitochondria through HSPA5 interaction. ER stress reduces secretion. Under the stress, minor amounts of non-secreted forms accumulate in cytoplasm.By similarity

Interactioni
Subunit structurei
Antiparallel disulfide-linked heterodimer of an alpha chain and a beta chain (PubMed:3415696). Self-associates and forms higher oligomers.
Interacts with a broad range of misfolded proteins, including APP, APOC2 and LYZ. Slightly acidic pH promotes interaction with misfolded proteins. Forms high-molecular weight oligomers upon interaction with misfolded proteins.
Interacts with APOA1, LRP2, CLUAP1 AND PON1.
Interacts with the complement complex.
Interacts (via alpha chain) with XRCC6.
Interacts with SYVN1, COMMD1, BTRC, CUL1 and with ubiquitin and SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complexes.
Interacts (via alpha chain) with BAX in stressed cells, where BAX undergoes a conformation change leading to association with the mitochondrial membrane. Does not interact with BAX in unstressed cells.
Found in a complex with LTF, CLU, EPPIN and SEMG1.
Interacts (immaturely glycosylated pre-secreted form) with HSPA5; this interaction promotes CLU stability and facilitates stress-induced CLU retrotranslocation from the secretory pathway to the mitochondria, thereby reducing stress-induced apoptosis by stabilizing mitochondrial membrane integrity.
Interacts with BCL2L1; this interaction releases and activates BAX and promotes cell death.
Interacts with TGFBR2 and ACVR1 (By similarity).
Interacts (secreted form) with STMN3; this interaction may act as an important modulator during neuronal differentiation (PubMed:16038898).
