產品詳情

  • 產品描述：

    The product CSB-PA740936ESR2HU is a polyclonal antibody produced in the rabbit with recombinant human NHLRC1 protein (1-280AA) immunized. This antibody against NHLRC1 exists as an unconjugated IgG. It is purified by the antigen affinity method. It shows reactivity with human and rat NHLRC1, also called EPM2B, which is an E3 ubiquitin-protein ligase that is complexed with EPM2A/laforin and HSP70 to inhibit the cellular toxicity of misfolded proteins by promoting their degradation through the ubiquitin-proteasome system (UPS). The NHLRC1 protein may play a vital role in the survival of neurons in the brain. This NHLRC1 antibody has been validated for use in ELISA, WB, and IHC applications.

靶點詳情

  • 功能：
    E3 ubiquitin-protein ligase. Together with the phosphatase EPM2A/laforin, appears to be involved in the clearance of toxic polyglucosan and protein aggregates via multiple pathways. In complex with EPM2A/laforin and HSP70, suppresses the cellular toxicity of misfolded proteins by promoting their degradation through the ubiquitin-proteasome system (UPS). Ubiquitinates the glycogen-targeting protein phosphatase subunits PPP1R3C/PTG and PPP1R3D in a laforin-dependent manner and targets them for proteasome-dependent degradation, thus decreasing glycogen accumulation. Polyubiquitinates EPM2A/laforin and ubiquitinates AGL and targets them for proteasome-dependent degradation. Also promotes proteasome-independent protein degradation through the macroautophagy pathway.
