描述：

TIAR Antibody检测内源性TIAR总蛋白水平。通过人工合成人源TIAR蛋白羧基末端周围相应的多肽片段去免疫动物从而制备多克隆抗体。通过蛋白A和多肽亲和层析纯化抗体。TIAR蛋白是一个RNA结合蛋白中RNA识别结构域(RRM)家族的成员(1,2)。在细胞内损伤的情况下，该蛋白的功能是作为一个翻译抑制性因子(3,4)。在细胞应激情况下，TIAR蛋白与eIF1、eIF3和40S核糖体亚基联系，并且形成非经典的翻译起始前复合物，该复合物不具备翻译活性 (3,4)。然后，TIAR蛋白能够与它的家族成员TIA1蛋白聚集，并且有助于蛋白质翻译失活的非经典起始前复合物进入被称为应激颗粒的离散细胞质颗粒中。TIAR蛋白的主要两个亚型是选择性mRNA剪切的产物 (5,6)。

原厂资料：

Specificity / Sensitivity

TIAR Antibody detects endogenous levels of total TIAR protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human TIAR. Antibodies are purified by protein A and peptide affinity chromatography.

Background

TIAR is a member of the RNA-recognition motif (RRM) family of RNA-binding proteins (1,2). It functions as a translational repressor under conditions of cellular damage (3,4). In response to cellular stress, TIAR associates with eIF1, eIF3, and the 40S ribosomal subunit and forms noncanonical preinitiation complexes that are translationally inactive (3,4). TIAR then aggregates with its family member TIA1 and facilitates the accumulation of the translationally inactive preinitiation complexes into discrete cytoplasmic foci called stress granules. The two major isoforms of TIAR are the products of alternative mRNA splicing (5,6).
