Human Gene SH3GLB1 (uc001dly.3) Description and Page Index
  Description: Homo sapiens SH3-domain GRB2-like endophilin B1 (SH3GLB1), transcript variant 2, mRNA.
RefSeq Summary (NM_001206651): This gene encodes a SRC homology 3 domain-containing protein. 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].

DESCRIPTION: RecName: Full=Endophilin-B1; AltName: Full=Bax-interacting factor 1; Short=Bif-1; AltName: Full=SH3 domain-containing GRB2-like protein B1;
FUNCTION: May be required for normal outer mitochondrial membrane dynamics. Required for coatomer-mediated retrograde transport in certain cells. May recruit other proteins to membranes with high curvature. May promote membrane fusion.
SUBUNIT: Binds DNM1, HTT, AMPH, BIN1 and ARFGAP1 (By similarity). Homodimer, and heterodimer with SH3GLB2. Binds BAX. Induction of apoptosis augments BAX binding.
INTERACTION: Self; NbExp=4; IntAct=EBI-2623095, EBI-2623095; Q07812:BAX; NbExp=2; IntAct=EBI-5291808, EBI-516580; P24522:GADD45A; NbExp=2; IntAct=EBI-2623095, EBI-448167; Q9NR46:SH3GLB2; NbExp=5; IntAct=EBI-2623095, EBI-749607;
SUBCELLULAR LOCATION: Cytoplasm. Golgi apparatus membrane; Peripheral membrane protein (By similarity). Mitochondrion outer membrane; Peripheral membrane protein. Note=Association with the Golgi apparatus depends on the cell type (By similarity).
TISSUE SPECIFICITY: Highly expressed in heart, skeletal muscle, kidney and placenta. Detected at lower levels in brain, colon, thymus, spleen, liver, small intestine, lung and peripheral blood leukocytes.
DOMAIN: An N-terminal amphipathic helix, the BAR domain and a second amphipathic helix inserted into helix 1 of the BAR domain (N-BAR domain) induce membrane curvature and bind curved membranes.
PTM: Phosphorylated at Thr-145 by CDK5; this phosphorylation is required for autophagy induction in starved neurons and facilitates homodimerization.
MISCELLANEOUS: HeLa cells lacking SH3GLB1 show dissociation of outer and inner mitochondrial membrane as well as abnormal mitochondrial morphology. Cells overexpressing SH3GLB1 lacking an N-terminal amphipathic helix show a similar phenotype.
MISCELLANEOUS: SH3GLB1 binds liposomes and induces formation of tubules from liposomes. SH3GLB1 lacking the N-terminal amphipathic helix fails to induce liposome tubulation.
SIMILARITY: Belongs to the endophilin family.
SIMILARITY: Contains 1 BAR domain.
SIMILARITY: Contains 1 SH3 domain.
CAUTION: It is uncertain whether Met-1 or Met-4 is the initiator.
CAUTION: Was originally (PubMed:12456676) thought to have lysophosphatidic acid acyltransferase activity, but by homology with SH3GL2/endophilin A1 is unlikely to have this activity.
SEQUENCE CAUTION: Sequence=AAF81225.1; Type=Erroneous initiation; Sequence=BAD88797.1; Type=Erroneous initiation;

ModBase Predicted Comparative 3D Structure on Q9Y371
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
