Human semen-specific γ-glutamyl transpeptidase active protein (SEGAP) is an enzyme complex of ubiquitinated CD10 and CD13. In this study, we investigated the potential of SEGAP to induce tyrosine-phosrchorylation in HeLa (human cervical carcinoma), Raji (human B cell lymphoma) and HL60 (human promyelocytic leukemia). FACS analysis of SEGAP-treated cells revealed that SEGAP may bind to these cells. Western blots of SEGAP-and anti-CD13 antibody-treated cell lysates were performed using an anti-phosphotyrosine antibody. Phosphorylation of 120-kDa and 55-kDa proteins in HeLa and HL60 were observed in 1-min and 5-min incubations with an anti-CD13 antibody. Since CD13 is not distributed in Raji, 120-kDa and 55-kDa proteins were not phosphorylated. SEGAP phosphorylated 110-kDa proteins during 1-min incubation in HeLa and 110-kDa, 70-kDa and 60-kDa proteins during 1-min incubation in HL60. These results suggested that SEGAP induces tyrosine-phosphorylations of 110-kDa, 70-kDa and 60-kDa proteins which are thought to be as PI3 kinase, Syk/ZAP-70 and Src family proteins, respectively. Messenger RNA levels of cytokines, lectins and apotosis related-proteins were also examined in SEGAP-treated HL60. SEGAP did not affect mRNA levels of IL1-β, IL8, Lyn, Fas and TNF.INF-γ and mannose-binding lectin RNAs were not expressed in HL60, and their levels were not affected by SEGAP.

人精液特异性 γ-谷氨酰转肽酶活性蛋白 (SEGAP) 是泛素化 CD10 和 CD13 的酶复合物。在这项研究中，我们研究了 SEGAP 在 HeLa（人宫颈癌）、Raji（人 B 细胞）中诱导酪氨酸磷酸化的潜力。 SEGAP 处理的细胞的 FACS 分析显示，SEGAP 可能是细胞淋巴瘤）和 HL60（人早幼粒细胞白血病）。使用抗磷酸酪氨酸抗体对 SEGAP 和抗 CD13 抗体处理的细胞裂解物进行蛋白质印迹，在 1 分钟和 5 分钟内观察到 HeLa 和 HL60 中 120 kDa 和 55 kDa 蛋白的磷酸化。由于 CD13 不分布在 Raji、120-kDa 和 55-kDa 中，因此与抗 CD13 抗体孵育 - 分钟。在 HeLa 中孵育 1 分钟期间，SEGAP 磷酸化 110-kDa 蛋白；在 HL60 中孵育 1 分钟期间，SEGAP 磷酸化 110-kDa 蛋白。这些结果表明，SEGAP 诱导 110 酪氨酸磷酸化。 -kDa、70-kDa 和 60-kDa 蛋白质被认为是还分别检测了 SEGAP 处理的 HL60 中细胞因子、凝集素和凋亡相关蛋白的 PI3 激酶、Syk/ZAP-70 和 Src 家族蛋白的 mRNA 水平。 、Fas和TNF。INF-γ和甘露糖结合凝集素RNA在HL60中不表达，并且它们的水平不受SEGAP影响。
