Biochem/physiol Actions
从糖蛋白上释放未取代的Ser-和Thr-连接β-Gal-(1→3)-α-GalNAc(核心1型O-聚糖)。 用唾液酸、乳糖胺(半乳糖-N-乙酰氨基葡萄糖)或岩藻糖取代的二糖核心将阻止水解并防止寡糖从蛋白质中释放出来。在使用O-糖苷酶切割之前,可能需要使用糖酵解酶进行预处理以从O-聚糖中去除取代糖。
Packaging
提供5×反应缓冲液,250mM NaH2PO4,pH 5.0。
Physical form
溶于50 mM磷酸钾,pH 7.5
Analysis Note

Glycoproteins with O-glycosidically linked carbohydrate chains of complex structures and functions are found in secretions and on the cell surfaces of cancer cells. The structures of O-glycans are often unusual or abnormal in cancer, and greatly contribute to the phenotype

The structures that contribute to shunt resistance (Rs) in esophageal epithelium are incompletely understood, with 35-40% of Rs known to be calcium-dependent, reflecting the role of e-cadherin. Two calcium-independent candidates for the remaining approximately 60% of Rs have been identified:
