Tag Info

C-terminal 10xHis-tagged
If you have specified tag type, please tell us and we will check if it’s possible to develop.

Form

Lyophilized powder
Note: We will default ship it in lyophilized form with normal bule ice packs. However, if you request to ship in liquid form, it needs to be shipped with dry ice, please communicate with us in advance and extra fees for dry ice and dry ice box will be charged.

Buffer

Lyophilized from PBS, 6% Trehalose, pH 7.4

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: Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.

Notes

Repeated freezing and thawing is not recommended. Store the protein at -20°C/-80°C upon receiving it, and ensure to avoid repeated freezing and thawing, otherwise, it will affect the protein activity.

Target Background

Function

G-protein coupled receptor which selectively activates G proteins via ultraviolet A (UVA) light-mediated activation in the skin. Binds both 11-cis retinal and all-trans retinal. Regulates melanogenesis in melanocytes via inhibition of alpha-MSH-induced MC1R-mediated cAMP signaling, modulation of calcium flux, regulation of CAMK2 phosphorylation, and subsequently phosphorylation of CREB, p38, ERK and MITF in response to blue light. Plays a role in melanocyte survival through regulation of intracellular calcium levels and subsequent BCL2/RAF1 signaling. Additionally regulates apoptosis via cytochrome c release and subsequent activation of the caspase cascade. Required for TYR and DCT blue light-induced complex formation in melanocytes. Involved in keratinocyte differentiation in response to blue-light. Required for the UVA-mediated induction of calcium and mitogen-activated protein kinase signaling resulting in the expression of MMP1, MMP2, MMP3, MMP9 and TIMP1 in dermal fibroblasts. Plays a role in light-mediated glucose uptake, mitochondrial respiration and fatty acid metabolism in brown adipocyte tissues. May be involved in photorelaxation of airway smooth muscle cells, via blue-light dependent GPCR signaling pathways.
