The total AP2 kit enables the cell-based quantitative detection of AP2, for monitoring GPCR activity. The Total AP2 cellular assay monitors total AP2 beta, and is used to detect the expression of endogenous or overexpressed AP2 beta in various cells. AP2 beta are components of the adaptor protein complex 2 (AP-2) and are known to n as cargo proteins. They play several roles in cells, including the internalization of GPCRs through a clathrin-dependent endocytosis process by direct interaction with beta arrestins. ons of AP2 beta ion cause specific dampening of cellular responses to stimuli such as hormones, neurotransmitters, or sensory signals. As AP2 essed in various tissues, it is believed that AP2 may play a major role in many cancers or other human diseases (diabetes) by ing receptor-mediated ns.
