SBP1/Selenium Binding Protein

钙结合蛋白calcium binding protein

广义的是指与钙离子进行特异结合的蛋白质之总称。与活体内钙的多种功能相应地有多种功能的蛋白质，可分别为以Ca 2 为活化因子的酶（血液凝固因子、各种蛋白酶、磷脂酶 A 2 和α - 淀粉酶等分解酶、膜的 Ca 2 运输 ATPase 、磷酸化酶 b 激酶）及无酶活性的两类，后者多称为狭义的钙结合蛋白，其中又分为：（ 1 ）与酶或细胞的机能调控有关的；（ 2 ）通过与 Ca 2 结合使游离的离子浓度降低，具有贮藏 Ca 的功能的。但也有功能未被测定的。肌宁蛋白 C 及调钙蛋白

Identifying Chromosomal Targets of DNA‐Binding Proteins by Sequence Tag Analysis of Genomic Enrichment (STAGE)

.3 ). Concatamers of tags are cloned and sequenced to yield a STAGE library. Tags in the library represent DNA fragments that were occupied by the DNA?binding protein, and mapping these tag sequences to the genome identifies the binding loci of the DNA?binding
