背景
功能:溶酶体膜糖蛋白在溶酶体生物发生、溶酶体 pH 调节和自噬中发挥重要作用 (PubMed:11082038, PubMed:18644871, PubMed:24880125, PubMed:27628032, PubMed:36586411, PubMed:37390818, PubMed:8662539)。它作为质子通道 TMEM175 的直接抑制剂,促进溶酶体酸化,从而发挥溶酶体腔 pH 调节的重要作用,以达到最佳水解酶活性 (PubMed:37390818)。在分子伴侣介导的自噬中发挥重要作用,自噬是一种响应各种应激以及作为长生物半衰期蛋白质正常周转的一部分而介导溶酶体降解蛋白质的过程 (PubMed:11082038, PubMed:18644871, PubMed:24880125, PubMed:27628032, PubMed:36586411, PubMed:8662539)。其功能是通过结合靶蛋白 (例如 GAPDH、NLRP3 和 MLLT11) 并将其靶向溶酶体降解 (PubMed:11082038, PubMed:18644871, PubMed:24880125, PubMed:36586411, PubMed:8662539)。在分子伴侣介导的自噬过程中,LAMP2 位于分子伴侣 (如 HSPA8/HSC70) 的下游,这些分子伴侣识别并结合底物蛋白,并介导底物蛋白募集至溶酶体,靶蛋白在溶酶体中与 LAMP2 结合 (PubMed:36586411)。LAMP2 在饥饿条件下参与溶酶体蛋白降解 (基于相似性)。自噬过程中,LAMP2 是自噬体与溶酶体融合所必需的 (PubMed:27628032)。缺乏 LAMP2 的细胞表达正常水平的 VAMP8,但无法在自噬体上积累 STX17,这很可能是自噬体与溶酶体融合缺失的原因 (PubMed:27628032)。LAMP2 也是自噬体内容物正常降解所必需的 (PubMed:27628032)。该蛋白通过其在溶酶体蛋白降解中的功能,对 MHC II 类分子介导的外源抗原的有效呈递至关重要;内体/溶酶体区室中蛋白酶产生的抗原肽会被新生 MHC II 亚基捕获 (PubMed:15894275, PubMed:20518820)。该蛋白并非 MHC II 类分子介导的内源抗原有效呈递所必需 (PubMed:20518820);该蛋白调节分子伴侣介导的自噬。该蛋白会降低 MHC II 对内源抗原的呈递。该蛋白不参与 MHC II 对胞外抗原和膜衍生抗原的呈递;(微生物感染) 该蛋白通过与 FURIN 以及未加工形式的腮腺炎病毒融合蛋白 F 相互作用,而非与加工形式的病毒蛋白 F 相互作用,从而促进 FURIN 介导的腮腺炎病毒融合蛋白 F 的切割。

诱导:在外周血 B 细胞中,LAMP-2A、LAMP-2B 和 LAMP-2C 同工型在通过 Toll 样受体 TLR7 或 TLR9 刺激免疫反应的治疗后表达上调。

  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
