摘要
应用^(125)I—钙调素(CAM)覆盖(Overlay)技术,从家兔阑尾(B细胞)、肠系膜淋巴结(T、B细胞)和脾脏(T、B细胞)淋巴细胞胞浆中分别检测到19、20和16种钙调素结合蛋白(CaMBP),其中均含有80、78、70、63、50、41、36、22、17和13.5KD CaMBP,以17KD和13.5KD CaMBP含量最为丰富,且与CaM结合呈部分钙依赖性。
Utilizing the ^(125)I-Calmodulin-overlay technique, we have detected calmodulin-binding proteins (CaMBPs) in crude extracts of lymphocytes. The results indicated that appendix (B cell), mesenteric lymph node (T, B cell) and spleen (T, B cell) from rabbit contained 19, 20 and 16 species of CaMBPs respectively. Ten CaMBPs with molecular weight 80, 78, 70, 63,50, 41, 36, 22, 17 and 13.5 K D were present in all lymphocytes detected. Lymphocytes were rich in two kind of CaMBPs with molecular weight 17 and 13.5 K D which bound calmodulin in partial calcium-dependent manner.
