LGR4

LGR4全称为富含亮氨酸重复序列的G蛋白偶联受体4,也被称为GPR48,是人体内调控多种生理过程的关键受体蛋白。该蛋白通过与R-spondin家族蛋白结合,激活Wnt/β-catenin信号系统,参与胚胎发育、干细胞自我更新及组织再生等核心生命活动。LGR4在肠道隐窝细胞增殖、骨骼代谢和生殖系统发育中具有重要作用,其功能异常可能导致结直肠癌、骨质疏松症及不孕症等疾病。例如,结直肠癌患者中常出现LGR4过度表达,通过激活Wnt通路驱动肿瘤生长;而基因敲除小鼠模型则显示骨密度显著下降。
近年来针对LGR4的药物开发聚焦于其配体相互作用环节,已有研究团队设计出阻断R-spondin与LGR4结合的小分子化合物,在动物实验中显示出抑制肿瘤生长的潜力。同时,基于LGR4在代谢调控中的作用,研究人员正探索其在糖尿病和肥胖治疗中的应用价值。

LGR4 Antibody (CSB-PA883618LA01HU)

验证数据

CSB-PA883618LA01HU

IHC image of CSB-PA883618LA01HU diluted at 1:100 and staining in paraffin-embedded human lung tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

CSB-PA883618LA01HU

Immunofluorescence staining of Hela cells with CSB-PA883618LA01HU at 1:100, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
