Immunogen A synthetic peptide from human Syntaxin-binding protein 5 (STXB5, Tomosyn-1, Llgl3) conjugated to an immunogenic carrier protein was used as the antigen.
Specificity Specific for Syntaxin-binding protein 5.
Purification Whole serum
Background Function: Inhibits translocation of GLUT4 from intracellular vesicles to the plasma membrane. Plays a regulatory role in calcium-dependent exocytosis and neurotransmitter release. Inhibits membrane fusion between transport vesicles and the plasma membrane. May modulate the assembly of trans-SNARE complexes between transport vesicles and the plasma membrane. Competes with STXBP1 for STX1 binding.
Subunit: Part of a complex that contains STXBP5, STX4A andSNAP23. Interacts with STX1A and STX4A via its v-SNARE homology domain. Part of a complex that contains STX1, STXBP5,SNAP25 and SYT1.
Subcellular location: Cytoplasm. Cell membrane, Peripheral membrane protein. Cytoplasmic vesicle membrane, Peripheral membrane protein. Cell junction, synapse. Cytoplasmic vesicle, secretory vesicle, synaptic vesicle. Note: Cytoplasmic, and associated with vesicular membranes and the plasma membrane. Detected at synapses and on synaptic vesicles.
Tissue specificity: Isoform 1 is detected in heart, brain, lung, liver, skeletal muscle, kidney and testis. Isoform 2 is detected in brain and in testis. Isoform 3 is detected in testis. Also known as: Lethal(2) giant larvae protein homolog 3, STXB5, Tomosyn-1, Llgl3.
Application Notes A dilution of 1 : 300 to 1 : 2000 is recommended.
The optimal dilution should be determined by the end user.
