Tag Info

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.

Form

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.

Buffer before Lyophilization

Tris/PBS-based buffer, 6% Trehalose.

Reconstitution

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.

Troubleshooting and FAQs

Protein FAQs

Storage Condition

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

Shelf Life

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.

Lead Time

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.

Notes

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

Target Background

Function

RAC1 GTPase activating protein (GAP) that binds and deforms membranes, and regulates actin dynamics to regulate cell migration and differentiation. Plays an important role in different aspects of neuronal morphogenesis and migration mainly during development of the cerebral cortex. This includes the biogenesis of neurites, where it is required for both axons and dendrites outgrowth, and the maturation of the dendritic spines. Also stimulates the branching of the leading process and negatively regulates neuron radial migration in the cerebral cortex. Its interaction and inhibition by SRGAP2C reduces the rate of spine maturation, alters dendritic spine morphology and density and indirectly increases neuronal migration. It may have implications for cognition, learning and memory. In non-neuronal cells, it may also play a role in cell migration by regulating the formation of lamellipodia and filopodia.

Gene References into Functions

Results show that in high-grade, stage II osteosarcoma samples, expression of SRGAP2 was substantially reduced or absent in over half of the samples. Functional analysis provides further evidence that SRGAP2 may have a role as a suppressor of metastases in osteosarcoma. PMID: 27966608
SRGAP2a protects podocytes in diabetic nephropathy by suppressing podocyte migration. PMID: 29242313
The extended F-BAR (F-BARx) domain of SRGAP2 generates membrane protrusions when expressed in COS-7 cells, while most F-BARs induce the opposite effect: membrane invaginations. As a first step to understand this discrepancy, the F-BARx domain of SRGAP2 was isolated and crystallized after co-expression with the carboxy domains of the protein. Diffraction data were reprocessed with a high-resolution cutoff of 2.2 A. PMID: 27917825
human-specific duplication of SRGAP2 might have contributed to the emergence of unique traits of human neurons while preserving the excitation/inhibition balance PMID: 27373832
This study illustrated that the role of SRGAP2 protein and its human-specific paralogs in human brain development and evolution. PMID: 23782070
interlocus gene conversions in SRGAP2 PMID: 23892896
SRGAP2 has been highly conserved over mammalian evolution, and human is the only lineage wherein gene duplications have occurred. Our analysis indicates that the duplications spread across 80 Mbp of chromosome 1 at a time corresponding to the transition from Australopithecus to Homo. PMID: 22559943
Results uncover a new function for ancestral SRGAP2 in promoting dendritic spine maturation and indicate that expression of a human-specific paralog of SRGAP2 in mouse pyramidal neurons extends the phase of spine development and leads to an increased density of longer spines in vivo, a feature characterizing pyramidal neurons in the human neocortex PMID: 22559944
after Rac-dependent activation of FMNL1, srGAP2 mediates a potent mechanism to limit the duration of Rac action and inhibit formin activity during rapid actin dynamics. PMID: 21148482
srGAP2 arginine methylation plays important roles in cell spreading and cell migration through influencing membrane protrusion. PMID: 20810653
FNBP2 gene was linked to IKBKE and NORE1 genes on human chromosome 1q32.1. FNBP2 mRNA was expressed in melanoma, germ cell tumors, chondrosarcoma and retinoblastoma. PMID: 12736724
