The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Predicted molecular weight: 26 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
FunctionRequired for the calcium-dependent exocytosis of signal sequence-containing cytokines such as CCL5. Probably acts in cooperation with the SNARE machinery. May play a role in accumulation of expanded polyglutamine (polyQ) protein huntingtin (HTT) in case of endoplasmic reticulum stress by inhibiting the endocytosis pathway.
Tissue specificityExpressed both by neuronal and nonneuronal tissues. Expressed in brain, stomach, thyroid, spinal cord, lymph node, trachea, adrenal gland, bone marrow and in the different parts of brain. In thyroid tissues, it is expressed by the follicular epithelial cells. In the adrenal gland tissues it is detected in the zona fasciculate of the cortex region (at protein level).
Sequence similaritiesBelongs to the SCAMP family. SCAMP5 subfamily.
Cellular localizationCell membrane. Golgi apparatus membrane. Golgi apparatus > trans-Golgi network membrane. Recycling endosome membrane. Cytoplasmic vesicle > secretory vesicle > synaptic vesicle membrane. Mainly localizes in Golgi apparatus membrane. Upon calcium-triggered exocytosis, it translocates to the cell membrane. Highly enriched in synaptic vesicles.
