1987年7月14日收到的修订稿摘要:用[125I]bpth(L-34)共价标记犬肾甲状旁腺激素受体,发现几个主要结合组分显示出与生理相关的腺苷环化酶连接受体一致的特征。通过使用特定的糖苷酶神经氨酸酶和内切糖苷酶F以及凝集素-琼脂糖凝胶亲和层析,我们证明该受体是一种糖蛋白,它含有几个复杂的N-连接碳水化合物链,由末端唾液酸和倒数第二个半乳糖组成,在01,4与TV-乙酰-D-氨基葡萄糖相连。不存在高甘露糖链或O-连接的多聚糖。脱糖标记受体的多肽分子量为62000[如果不包括BPTH(L-34)的质量,则为58000]。~(125)I]BPTH(L-34)与受体的结合可被麦胚凝集素以剂量依赖的方式抑制,但不能被琥珀酸化的麦胚凝集素或蓖麻凝集素所抑制,提示末端唾液酸可能参与激动剂的结合。
Revised Manuscript Received July 14, 1987 abstract: Covalent labeling of the canine renalparathyroid hormone receptor with [125I] bPTH (l-34) reveals several major binding components that display characteristics consistent with a physiologically relevant adenylate cyclase linked receptor. Through the use of the specific glycosidases neuraminidase and endoglycosidase F and affinity chromatography on lectin-agarose gels, we show here that the receptor is a glycoprotein that contains several complex N-linked carbohydrate chains consisting of terminalsialic acid and penultimate galactose in a 01, 4 linkage to TV-acetyl-D-glucosamine. No high mannose chains or O-linked glycans appear to be present. The peptide molecular weight of the deglycosylated labeled receptor is 62 000 [or 58 000 if the mass of bPTH (l-34) is excluded]. The binding of [125I] bPTH (l-34) to the receptor is inhibited in a dose-dependent fashion by wheat-germ agglutinin, but not by either succinylated wheat-germ agglutinin or Ricinus communis lectin, suggesting that terminal sialicacid may be involved in agonist binding.
