FAP 抗体

品牌：MedChemExpress (MCE)

货号：HY-P86673

存储条件：-20°C保存1年。避免重复冻结/解冻循环。

运输条件：用蓝冰运输。

产品活性：FAP Antibody (YA6365) 是一种兔源、无偶联标记、抗 FAP 的 IgG 单克隆抗体。它可用于人背景下的 WB 实验。

研究背景：FAP 蛋白是一种细胞表面糖蛋白丝氨酸蛋白酶，在细胞外基质降解中起着至关重要的作用，并参与多种细胞过程，包括组织重塑、纤维化、伤口愈合、炎症和肿瘤生长。FAP 的质膜和可溶形式均表现出脯氨酸后裂解内肽酶活性，表明对底物（如 α-2-抗纤溶酶 SERPINF2 和 SPRY2）上的 Ala/Ser-Gly-Pro-Ser/Asn/Ala 共有序列有偏好。FAP 可以降解明胶、热变性 I 型胶原蛋白和各种其他底物。此外，它还具有二肽基肽酶活性，可优先水解合成二肽底物中的脯氨酰键，并优先选择特定氨基酸序列。与 DPP4、PLAUR 或整合素相关，FAP 的质膜形式参与细胞外基质的细胞周蛋白水解，促进细胞粘附、迁移和侵袭。FAP 的多方面功能延伸至发育和伤口愈合过程中的组织重塑。在恶性黑色素瘤中，FAP 增强细胞对细胞外基质的侵袭性，并通过降解蛋白多糖短聚糖促进神经胶质瘤细胞侵入脑实质。FAP 通过增加血管生成、胶原纤维降解和细胞凋亡来促进肿瘤生长进展，但矛盾的是，FAP 通过以丝氨酸蛋白酶活性独立的方式调节细胞增殖和存活，在黑素细胞中充当肿瘤抑制因子。

亚细胞定位：Prolyl endopeptidase FAP: Cell surface.Cell membrane. Cell projection, lamellipodium membrane; Single-pass type II membrane protein. Cell projection, invadopodium membrane; Single-pass type II membrane protein. Cell projection, ruffle membrane; Single-pass type II membrane protein. Membrane {ECO:0000269|PubMed:2172980}; Single-pass type II membrane protein {ECO:0000255}. Note=Localized on cell surface with lamellipodia and invadopodia membranes and on shed vesicles. Colocalized with DPP4 at invadopodia and lamellipodia membranes of migratory activated endothelial cells in collagenous matrix. Colocalized with DPP4 on endothelial cells of capillary-like microvessels but not large vessels within invasive breast ductal carcinoma. Anchored and enriched preferentially by integrin alpha-3/beta-1 at invadopodia, plasma membrane protrusions that correspond to sites of cell invasion, in a collagen-dependent manner. Localized at plasma and ruffle membranes in a collagen-independent manner. Colocalized with PLAUR preferentially at the cell surface of invadopodia membranes in a cytoskeleton-, integrin- and vitronectin-dependent manner. Concentrated at invadopodia membranes, specialized protrusions of the ventral plasma membrane in a fibrobectin-dependent manner. Colocalizes with extracellular components (ECM), such as collagen fibers and fibronectin.Antiplasmin-cleaving enzyme FAP, soluble form: Secreted. Note=Found in blood plasma and serum.
