分子别名(Synonym)

CD113,Nectin-3,PVRL3

表达区间及表达系统(Source)

Biotinylated Human Nectin-3, Fc,Avitag (PV3-H82F3) is expressed from human 293 cells (HEK293). It contains AA Gly 58 - Asp 400 (Accession # Q9NQS3-1).

Predicted N-terminus: Leu 56 & Gly 58

蛋白结构(Molecular Characterization)

Online(Gly 58 - Asp 400) Q9NQS3-1

This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag (Avitag™).

The protein has a calculated MW of 66.1 kDa. The protein migrates as 90-95 kDa and 100-115 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记(Biotinylation)

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白标记度(Biotin:Protein Ratio)

The biotin to protein ratio is 0.5-1 as determined by the HABA assay.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Protocol

背景(Background)

Poliovirus receptor-related 3 (PVRL3), also known as nectin-3 and CD113, is a human protein of the immunoglobulin superfamily which forms part of adherens junctions. Nectins are immunoglobulin-like adhesion molecules that interact with afadin (AF6; MIM 159559). Afadin is an actin filament-binding protein that connects nectins to the actin cytoskeleton. The nectin-afadin system organizes adherens junctions cooperatively with the cadherin system in epithelial cells. PVRL3 plays a role in cell-cell adhesion through heterophilic trans-interactions with nectin-like proteins or nectins, such as trans-interaction with PVRL2/nectin-2 at Sertoli-spermatid junctions. Furthermore, PVRL3 induces endocytosis-mediated down-regulation of PVR from the cell surface, resulting in reduction of cell movement and proliferation.
