    产品编号bs-12126P
    英文名称STXBP5 Antibody Blocking Peptide
    中文名称突触融合蛋白结合蛋白5封闭多肽
    英文别名FLJ30922; Lethal(2) giant larvae protein homolog 3; LGL3; LLGL3; MGC141942; MGC141968; Nbla04300; STXBP5; Syntaxin binding protein 5; Syntaxin-binding protein 5; Tomosyn 1; STXB5_HUMAN.
    纯化方法HPLC
    亚基Interacts with STX1A and STX1B via its v-SNARE homology domain. Part of a complex that contains STX1, STXBP5, SNAP25 and SYT1. Part of a complex that contains STXBP5, STX4A and SNAP23.
    亚细胞定位Cytoplasm. Cell membrane; Peripheral membrane protein. Cytoplasmic vesicle membrane; Peripheral membrane protein. Cytoplasmic vesicle, secretory vesicle, synaptic vesicle. Cell junction, synapse. Note=Cytoplasmic, and associated with vesicular membranes and the plasma membrane. Detected at synapses and on synaptic vesicles.
    相似性Belongs to the WD repeat L(2)GL family.
    Contains 1 v-SNARE coiled-coil homology domain.
    Contains 14 WD repeats.
    功能Tomosyn plays a regulatory role in calcium-dependent exocytosis and neurotransmitter release by inhibiting the assembly of trans-SNARE complexes between transport vesicles and the plasma membrane, via the displacement of munc18 from syntaxin-1. There are three splice variants of tomosyn designated m-tomosyn, b-tomosyn and s-tomosyn. Although b-tomosyn is ubiquitously expressed, s-tomosyn and m-tomosyn are expressed primarily in brain.
    保存条件Shipped at 4℃. Stored at -20℃ for one year. Avoid repeated freeze/thaw cycles.
    注意事项This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications.
    背景资料WD-repeats are motifs that are found in a variety of proteins and are characterized by a conserved core of 40-60 amino acids that commonly form a tertiary propeller structure. While proteins that contain WD-repeats participate in a wide range of cellular functions, they are generally involved in regulatory mechanisms concerning chromatin assembly, cell cycle control, signal transduction, RNA processing, apoptosis and vesicular trafficking. Tomosyn, also known as STXBP5 (syntaxin binding protein 5), LLGL3 or LGL3, is a 1,151 amino acid protein that localizes to the cytoplasm, as well as to the cell junction, secretory vesicles and to the peripheral membrane and contains one v-SNARE coiled-coil homology domain and 14 WD repeats. Interacting with Syntaxin 1 and Syntaxin 1B, Tomosyn functions as a regulator of neurotransmitter release and calcium-dependent exocytosis. Additionally, Tomosyn inhibits membrane fusion and may play a role in the assembly of SNARE complexes between transport vesicles and the plasma membrane. Multiple isoforms of Tomosyn exist due to alternative splicing events.
