Tag?type?will?be?determined?during?the?manufacturing?process.

The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
產品提供形式：

Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
復溶：

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點詳情

功能：

Ca(2+)-binding protein that plays a key role in store-operated Ca(2+) entry (SOCE) in T-cells by regulating CRAC channel activation. Acts as a cytoplasmic calcium-sensor that facilitates the clustering of ORAI1 and STIM1 at the junctional regions between the plasma membrane and the endoplasmic reticulum upon low Ca(2+) concentration. It thereby regulates CRAC channel activation, including translocation and clustering of ORAI1 and STIM1. Upon increase of cytoplasmic Ca(2+) resulting from opening of CRAC channels, dissociates from ORAI1 and STIM1, thereby destabilizing the ORAI1-STIM1 complex.; Rab GTPase that mediates the trafficking of Weibel-Palade bodies (WPBs) to microtubule organizing center (MTOC) in endothelial cells in response to acute inflammatory stimuli. During histamine (but not thrombin) stimulation of endothelial cells, the dynein-bound form induces retrograde transport of a subset of WPBs along microtubules to the MTOC in a Ca(2+)-independent manner and its GTPase activity is essential for this function. Ca(2+)-regulated dynein adapter protein that activates dynein-mediated transport and dynein-dynactin motility on microtubules and regulates endosomal trafficking of CD47. Acts as an intracellular signaling module bridging two important T-cell receptor (TCR) signaling pathways, Ca(2+)-NFAT and JNK, to affect T-cell activation. In resting T-cells, is predominantly localized near TGN network in a GTP-bound form, upon TCR stimulation, localizes at the immunological synapse via interaction with VAV1 to activate downstream Ca(2+)-NFAT and JNK signaling pathways. Plays a role in T-helper 1 (Th1) cell differentiation and T-helper 17 (Th17) cell effector function. Plays a role in store-operated Ca(2+) entry (SOCE) in T-cells by regulating CRAC channel activation.
基因功能參考文獻：
1. Results show the characterization of CRACR2A protein which encodes a large Rab GTPase containing multiple functional domains contrary to small Rab GTPases. It was found to play an unexpected role in regulating intracellular signaling pathways important for T cell activation. PMID: 27221160
2. GTP binding and prenylation of CRACR2A were associated with its localization near the Golgi and its stability PMID: 27016526
3. endothelial cells contain a long variant of CRACR2A which is an EF-hand-containing Rab protein that lacks impact on CRAC channels PMID: 25475730
4. CRACR2A interacts directly with Orai1 and STIM1, forming a ternary complex that dissociates at elevated Ca(2+) concentrations; is a key regulator of CRAC channel-mediated SOCE PMID: 20418871
