Summary: Enables fatty acid binding activity; lysophosphatidic acid acyltransferase activity; and phosphatidylinositol 3-kinase activator activity. Involved in several processes, including autophagic cell death; positive regulation of autophagosome assembly; and regulation of intrinsic apoptotic signaling pathway by p53 class mediator. Acts upstream of or within 'de novo' post-translational protein folding; phosphatidic acid biosynthetic process; and positive regulation of establishment of protein localization to mitochondrion. Located in membrane. Part of protein-containing complex. Is expressed in several structures, including cerebellum; cerebral cortex; otocyst; and spleen. Orthologous to human SH3GLB1 (SH3 domain containing GRB2 like, endophilin B1). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
