描述：

β-Catenin (D10A8) XP^® Rabbit mAb（偶联琼脂糖珠子）可以识别内源性的总β-catenin蛋白。此单克隆抗体由合成肽段免疫动物产生，该肽段与人β-catenin蛋白的Pro714邻近氨基酸残基序列一致。此CST抗体通过将原始氨基酸序列与N-hydroxysuccinimide (NHS)-活化的琼脂糖珠子共价结合获得。β-Catenin (D10A8) XP^®Rabbit mAb兔单抗（偶联琼脂糖珠子）用于免疫沉淀β-catenin。抗体被认为与未偶联的β-Catenin (D10A8) XP^® Rabbit mAb#8480兔单抗有相同的交叉反应。β-catenin是Wnt信号通路下游的重要效应分子（1）。在脊椎动物体内它涉及到两个重要的生物过程：早期胚胎发育（2）和肿瘤发生（3）。CK1可以磷酸化β-catenin 45位丝氨酸。该磷酸化将导致β-catenin能够随后被GSK-3磷酸化（4-6）。GSK-3β通过磷酸化β-catenin Ser33, Ser37, 和 Thr41，并促使其进一步被降解（7）。这些位点发生突变会提高β-catenin蛋白稳定性，并且已在多种癌细胞株中发现这些突变（8）。

Homology

Species predicted to react based on 100% sequence homology: Zebrafish, Bovine, Pig, Guinea Pig, Horse

Specificity / Sensitivity

β-Catenin (D10A8) XP^® Rabbit mAb (Sepharose Bead Conjugate) recognizes endogenous levels of total β-catenin protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro714 of human β-catenin protein。

Description

This Cell Signaling Technology antibody is immobilized via covalent binding of primary amino groups to N-hydroxysuccinimide (NHS)-activated sepharose beads. β-Catenin (D10A8) XP® Rabbit mAb (Sepharose Bead Conjugate) is useful for the immunoprecipitation of β-catenin. The antibody is expected to exhibit the same species cross-reactivity as the unconjugated β-Catenin (D10A8) XP® Rabbit mAb #8480.

Background

β-Catenin is a key downstream effector in the Wnt signaling pathway (1). It is implicated in two major biological processes in vertebrates: early embryonic development (2) and tumorigenesis (3). CK1 phosphorylates β-catenin at Ser45. This phosphorylation event primes β-catenin for subsequent phosphorylation by GSK-3β (4-6). GSK-3β destabilizes β-catenin by phosphorylating it at Ser33, Ser37, and Thr41 (7). Mutations at these sites result in the stabilization of β-catenin protein levels and have been found in many tumor cell lines (8).
