描述：

Oct-1抗体可以识别内源性的总Oct-1蛋白。合成与邻近人源Oct-1蛋白的Leu362 氨基酸残基序列一致的肽段，免疫动物获得多克隆抗体。抗体由蛋白A和肽段亲和层析法纯化。Oct-1 (POU2F1)是一个广泛表达，以八聚体形式发挥作用的转录因子，它带有一个内含同源序列的POU结构域（1）。Oct-1可以通过与一些转录因子结合介导特异基因表达，包括SNAPc（2），OBF-1 (a B-cell 转录辅助激活蛋白) (3), TFIIB (4), 和TBP (TATA-box结合蛋白) (5)。其带有的POU的 DNA结合结构域使Oct-1能够结合与招募一些组织特异性的辅助因子以正向或负向地调控不同的基因，在发育过程中发挥重要作用（6）。

原厂资料：

Specificity / Sensitivity

Oct-1 Antibody detects endogenous levels of total Oct-1 protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to amino acids surrounding Leu362 of human Oct-1. Antibodies are purified by protein A and peptide affinity chromatography.

Background

Oct-1 (POU2F1) is a ubiquitously expressed, octamer-binding transcription factor containing a POU domain with a homeobox subdomain (1). Oct-1 has been shown to interact with several transcription factors in mediating specific gene expression, including SNAPc (2), OBF-1 (a B-cell transcriptional coactivator protein) (3), TFIIB (4), and TBP (TATA-box-binding protein) (5). Its POU DNA-binding domain allows Oct-1 the flexibility to facilitate the binding and recruitment of several tissue-specific cofactors to either positively or negatively regulate a variety of genes, exerting an important role in development (6).
