The encoded protein interacts with the proapoptotic member of the Bcl-2 family, Bcl-2-associated X protein (Bax) and may be involved in regulating apoptotic signaling pathways. This protein may also be involved in maintaining mitochondrial morphology. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2011]. * **UniProt Summary**: May be required for normal outer mitochondrial membrane dynamics (PubMed:15452144). Required for coatomer-mediated retrograde transport in certain cells (By similarity). May recruit other proteins to membranes with high curvature. May promote membrane fusion (PubMed:11604418). Involved in activation of caspase-dependent apoptosis by promoting BAX/BAK1 activation (PubMed:16227588). Isoform 1 acts proapoptotic in fibroblasts (By similarity). Involved in caspase-independent apoptosis during nutrition starvation and involved in the regulation of autophagy. Activates lipid kinase activity of PIK3C3 during autophagy probably by associating with the PI3K complex II (PI3KC3-C2) (PubMed:17891140). Associated with PI3KC3-C2 during autophagy may regulate the trafficking of ATG9A from the Golgi complex to the peripheral cytoplasm for the formation of autophagosomes by inducing Golgi membrane tubulation and fragmentation (PubMed:21068542). Involved in regulation of degradative endocytic trafficking and cytokinesis, probably in the context of PI3KC3-C2 (PubMed:20643123). Isoform 2 acts antiapoptotic in neuronal cells; involved in maintenance of mitochondrial morphology and promotes neuronal viability (By similarity). {ECO:0000250|UniProtKB:Q9JK48, ECO:0000269|PubMed:11604418, ECO:0000269|PubMed:15452144, ECO:0000269|PubMed:17891140, ECO:0000269|PubMed:20643123, ECO:0000269|PubMed:21068542}. |SH3 2| |BAR| |SH3 1| |BAR 2| |protein localization to vacuolar membrane| |positive regulation of membrane tubulation| |regulation of membrane tubulation| |autophagic cell death| |positive regulation of autophagosome assembly| |membrane fission| |positive regulation of vacuole organization| |regulation of plasma membrane organization| |positive regulation of protein oligomerization| |receptor catabolic process| |positive regulation of protein targeting to mitochondrion| |autophagosome membrane| |regulation of autophagosome assembly| |cellular response to glucose starvation| |regulation of vacuole organization| |regulation of protein oligomerization| |cellular response to amino acid starvation| |regulation of protein targeting to mitochondrion| |response to amino acid starvation| |positive regulation of establishment of protein localization to mitochondrion| |protein localization to vacuole| |positive regulation of macroautophagy| |regulation of establishment of protein localization to mitochondrion| |positive regulation of organelle assembly| |regulation of protein targeting| |regulation of cytokinesis| |receptor metabolic process| |positive regulation of mitochondrion organization| |positive regulation of autophagy| |cellular response to starvation| |positive regulation of intracellular protein transport| |lipid binding| |midbody| |mitochondrial outer membrane| |regulation of cell division| |regulation of macroautophagy| |regulation of mitochondrion organization| |response to starvation| |positive regulation of intracellular transport| |regulation of organelle assembly| |regulation of intracellular protein transport| |cellular response to nutrient levels| |positive regulation of protein complex assembly| |cytoplasmic vesicle| |process utilizing autophagic mechanism| |autophagy| |cellular response to extracellular stimulus| |regulation of protein stability| |cadherin binding| |positive regulation of cellular protein localization| |regulation of autophagy| |cellular response to external stimulus| |regulation of intracellular transport| |positive regulation of cellular catabolic process| |positive regulation of protein transport| |positive regulation of catabolic process| |regulation of protein complex assembly| |positive regulation of establishment of protein localization| |protein localization to membrane| |response to nutrient levels| |protein complex oligomerization| |positive regulation of cellular component biogenesis| |response to extracellular stimulus| |regulation of cellular protein localization| |Golgi membrane| |positive regulation of organelle organization| |regulation of protein transport| |protein localization to organelle| |regulation of peptide transport| |regulation of establishment of protein localization| |regulation of cell cycle process| |regulation of cellular catabolic process| |membrane organization| |protein homodimerization activity| |regulation of cellular localization| |apoptotic process| |regulation of cellular component biogenesis| |positive regulation of transport| |regulation of catabolic process| |regulation of protein localization| |macromolecule catabolic process| |programmed cell death| |identical protein binding| |cell death| |regulation of cell cycle| |positive regulation of cellular component organization| |regulation of organelle organization| |protein-containing complex assembly| |cellular protein localization| |cellular macromolecule localization| |cellular response to stress| |organic substance catabolic process| |cellular catabolic process| |protein-containing complex subunit organization| |regulation of transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp471|Cholesterol 0.003 to 0.006 to 0.1μM on day2 then day6 R08 exp471]]|-1.77| |[[:results:exp85|UM0129480 7μM R02 exp85]]|-1.77| |[[:results:exp143|Phenformin 20μM R03 exp143]]|-1.73| |[[:results:exp335|Aminopterin 0.005μM R07 exp335]]|1.71| |[[:results:exp208|Vinblastine 0.015μM R05 exp208]]|1.79| |[[:results:exp465|Cannabidiol 13μM R08 exp465]]|2.04| No correlation found to any other genes in chemogenomics.
